My Comments

At the moment, there is the latest generation of the Bose QuietComfort 35 noise-cancelling Bluetooth headset that implements a software link with the Google Assistant voice driven personal assistants through its own app. Now Bang & Olufsen have come up with the Beosound A1 Second Generation battery-operated Bluetooth speaker that has integration with the Amazon Alexa voice-driven home assistant platform.

But what are these about?

How the likes of the B&O Beosound A1 work with your smartphone, tablet or computer to be a smart speaker

These are purely Bluetooth audio peripherals that connect to your smartphone which links with the Internet via Wi-Fi or mobile broadband. This is usually facilitated with a manufacturer-supplied app for that device that you install on your smartphone or tablet. You will also have to install the client software for the voice-driven assistant platform if your smartphone or tablet doesn’t have inherent support for that platform.

The Bose solution primarily used their app to “map” a secondary function button on the headset to activate Google Assistant. Then the B&O approach had the Beosound A1 and your smartphone or similar mobile-platform device work together as if it is an Amazon Echo.

Why do I see this as a significant trend for “smart-speaker” and allied device use cases, especially as Google, Amazon and the Voice Interoperability Initiative want to extend their voice-driven assistant platforms to setups based around Bluetooth audio peripherals. Here it underscores the reality that the highly-capable host devices will have Internet connectivity via a mobile-broadband connection or a local-area network.

One is to allow manufacturers to provide a highly-portable approach towards using Alexa or Google Assistant while on the move. Similarly, this approach will appeal to those in the automotive and marine infotainment sector with the idea of end-users bringing their own Internet connection with them while in their car or boat but wanting to use their preferred voice-driven assistant platform there.

Some technology manufacturers may look at the idea of a two-piece setup with a specially-designed Bluetooth speaker that links with a device that is normally connected to the Internet like a set-top box or router and both devices working in a smart-speaker capacity. Here, it can be about a cost-effective smart-speaker platform or to enable the use of battery-operated devices that use battery-efficient technologies.

After what Bose and B&O are doing, it could be about bringing the idea of a two-box smart-speaker setup for voice-driven assistant platforms opening up some interesting pathways.

Smart speakers and broadcast radio

Smart speakers like the Amazon Echo are outselling traditional radios

The traditional radio broadcast industry are finding that the smart speaker as a threat to their business models.

This is because that there are more Amazon Echo, Google Home or similar smart speakers being bought than traditional radio sets. It is in addition to us using smartphones that don’t have traditional broadcast-radio tuners as our “go-to” information and entertainment devices.

Although these smart speakers can, at your voice command, pull up a traditional radio station thanks to TuneIn or similar Internet-radio directories, an increasing number of users are using them to summon podcasts or music playlists through the various podcast and music-on-demand services.

Pure Sensia 200D Connect Internet radio – an example of how to keep the traditional radio relevant

At the moment, traditional radio whether through traditional broadcast technology or Internet streaming is primarily being listened to in the car or at businesses we frequent. It is also being seen, whether for information or entertainment, as a valid casual-listening content-source by Generation X (people born from the late 60s to the early 80s) and prior generations thanks to it being seen that way for a long time. This is due to the ubiquity of increasingly-affordable radio sets in many different form factors along with radio stations making a strong effort to keep listeners tuned to their output.

It is although advertisers and others have seen and are seeing the younger generations as “where the money is”. Here, they end up sponsoring podcasts or playlists to reach that audience with their message in order to stay relevant.

ABC Radio Podcasts

The ABC, like other traditional broadcasters, are offering their own podcasts, whether to do with an existing radio show or not

But what can be or is being done about this? At the moment, traditional radio stations are creating podcasts, whether as a byproduct of an existing radio show or as a new product. Similarly as I have experienced, most radio stations are planting their regular broadcast output on the Internet and making sure this still happens so as to work with smartphones and smart speakers. It is even though they face battles with music rightsholders and sporting leagues about international streaming rights for music or sports content.

RadioDNS “hybrid radio” has surfaced as a way to bring together traditional radio and the Internet. The key method offered by this platform is through a “single-dial” approach that provides a seamless handover between local radio frequencies / DAB multiplex locations and Internet streams for the same radio station.

This Internet radio is tuned in to Heart London and is playing the same audio as what would be delivered on FM or DAB from the “Turn Up The Feel Good” station within the London area

Reliance on Internet audio streams as often done with smart speakers and smartphones can be problemsome if you don’t have the right kind of network and Internet connection. This represents the typical home or small-business network connected behind most home / small-business routers.

You will run in to problems with setting up a smart speaker or similar device to work with a headline public-access / guest-access Wi-Fi network that depends on Web-based authentication or having these devices work with an enterprise-grade network that uses per-device-based authentication approaches. It also includes dealing with mobile broadband services that charge an arm and a leg for continual bandwidth use but services that operate in a highly-competitive market may make this factor easier.

The stations listed on the TuneIn Internet radio app are the Internet-hosted simulcast stream of their regular radio output

Similarly broadcast-radio technology tends to appeal to listenership on battery-operated devices because the technology associated with it is optimised to work for battery efficiency. It is due to the broadcast-radio technology working on a one-way approach to receiving the radio signals rather than being dependent on a two-way transceiver demanded of Wi-Fi or mobile-broadband.

What can be done to bridge these technologies

One approach would be to have an Internet radio that also receives radio content via broadcast technologies work with at least one of the common voice-driven home assistant platforms.

This can be in the form of the radio working alongside a smart speaker based on the common platforms and using RadioDNS to pull up local radio stations under voice control.

An Internet radio can also serve as a speaker for online audio resources like on-demand music services, podcasts and Internet radio especially if the radio doesn’t have network-audio / Internet-radio functionality. The latter concept is being underscored with the Google Assistant platform where you can direct audio from an online-audio service to a device that supports the Google Chromecast protocol. Even if the radio has network-audio / Internet-radio functionality, it could be part of a voice-driven home-assistant platform, which a lot of manufacturers are heading towards and can be of relevance for the “big sets” like hi-fi systems and the network multiroom audio platforms.

A cheaper option could implement RadioDNS across a Bluetooth link with the voice-driven home assistant platform handling the RadioDNS logic. It may require the creation of a Bluetooth profile for sending RadioDNS-specific data between the radio and the smart speaker’s platform i.e. a set-appropriate pointer to the station on the broadcast bands.

It can also be about an Internet-radio / smart-speaker combination device, like the many combination devices available over the years that integrated radio reception and at least one other function. Such a set would have the ability to be an Internet radio but it would have a microphone array and a button to activate Amazon Alexa or Google Assistant, whereupon you would have the full “smart speaker” abilities of an Amazon Echo or Google Home speaker. As well, it would tie in with the RadioDNS functionality to pull up stations on the local wavebands as if you are pulling them up using the assistant’s Internet-radio functionality.

Conclusion

To keep the classic radio medium going, the manufacturers, broadcasters and other stakeholders need to look at whatever technologies can be used to make it relevant in this day and age.

Nest Mini brings twice the bass and an upgraded Assistant (Product Blog Post)

My Comments

The Google Nest Mini smart speaker, which is the successor to the Google Home Mini smart speaker, shows up a significant number of improvements including a richer sound. But it has also come about with the idea of locally processing your voice commands for better Google Assistant performance.

The traditional approach to processing voice commands that are said to a smart speaker or similar device is for that device to send them out as a voice recording to the cloud servers that are part of the voice-driven assistant platform. These servers then implement their artificial-intelligence and machine-learning technology to strip background noise, interpret the commands and supply the appropriate replies or actions back to that device.

But Google has improved on this by using a leaf out of the book associated with edge-computing technology. This is where some of the data storage or processing is performed local to the user before the data is sent to a cloud computing system. Here, Google uses a dedicated machine-language processor chip in their Nest Mini smart speaker to do some of the command processing before sending data about the user’s command to the Google Assistant cloud system.

It reduces the idea of your Google Nest Mini smart speaker being a simple conduit between your home network and the Google Assistant cloud. The key benefit is that you see a quicker response from the Google Assistant via that device. You also have the benefit of reducing the Internet bandwidth associated with handling the voice-driven home assistant activity, avoiding reduced performance for online gaming or multimedia streaming.

Google is working on taking this further with having Google-Assistant-based devices that have this kind of local processing process logic associated with user requests and programmable actions locally. It also includes keeping the logic associated with the Assistant liaising with other smart devices local to your home network, allowing for improvements to performance, user privacy and data security.

It could be seen by Amazon and others as a way to improve the performance of their voice-driven home-assistant platforms. This is more so where the competition between these platforms becomes more keen. As well, there could be a chance for third-party Google Assistant (Home) implementations to look towards using local processing to improve the Assistant’s response.

An issue that will crop up is having multiple devices that have this kind of local processing existing on the same home network help each other to increase the voice-driven assistant’s performance. This can also include using a software approach to make the devices equipped with the local processing provide improved performance for those that don’t have this processing. It will be an issue with the likes of Google Nest Mini and similar entry-level devices that appeal to the idea of having many installed around the house, along with the idea of equipping smart displays with this kind of local processing.

What I see of this is that the use of edge-computing technology is coming to the fore as far as improving responsiveness in the common voice-driven home-assistant platforms.

Using Google Assistant as part of an in-home-care service

The Google Home now part of ageing-at-home and working with a home healthcare service

Feros Care plugs into Google Assistant to boost seniors’ independence | IT News]

My Comments

The technology industry is working on making themselves relevant to the “ageing-at-home” sector where senior citizens, including the ageing Baby Boomer population, can live in their own homes or in supported accommodation but preserve their own privacy and dignity. But the goal of improved dignity for these seniors includes using the technology that doesn’t look out of place in an ordinary home environment.

This system, ran by Feros Care, implements Google Assistant technology as a base platform and uses Google Home smart-speaker devices as a voice-driven interface with the client who the agency is looking after. It also facilitates visual display through the Android TV smart-TV platform and the Google Home Hub smart display.

This is facilitated through the development of Google Actions and DialogFlow natural-language processing with some custom application-programming-interface (API) software “hooks” to work with the agency’s MyFeros IT portal. It provides the client access access to details about carer appoints, further assistance amongst other things while the MyFeros portal captures service-provider to client interactions.

It is more about allowing senior citizens who use this agency for assisted living to manage their experience with the agency themselves and maintain their independence.

The use of the Google Home / Assistant voice-interaction technology can work around situations where the senior has had a fall and cannot gain access to the phone to summon help. Similarly it works well when they are recovering in bed and don’t have a tablet or phone at their bedside. The Android TV / Home Hub smart-TV technology can be used to show up visual information like details of alternate carers who are “filling in” for a regular carer who is ill or on leave and cannot attend

Even smart-lock technology is coming in to play in order to allow staff who are rostered on to care for a particular client access to that client’s home for the duration of their shift. This is due to older people with limited mobility taking a long time to reach their front door to admit the carer in to their home. The smart-lock integration will also work in hand with “visit-verification” requirements that will be demanded within the home-based healthcare industry thanks to various health-insurance or public-healthcare requirements.

Feros Care underscores that the technology is not about staff efficiency and productivity by to serve the needs of their service’s end-users and protect their dignity and independence.

But what I like about this approach is that they aren’t reinventing the wheel in implementing this technology and having to implement new devices for their field of work. Rather they use common “horizontal-market” technology like Google-Home-compatible smart speakers and smart displays compliant with Google’s smart-display technologies – such equipment able to be purchased “off the shelf” at any consumer electronics outlet and blend in to an ordinary home.

I also see Feros Care in a position to offer the necessary software logic as a “white-label” solution for all sorts of home healthcare agencies, supported-housing facilities and the like who want to implement it in their client-carer IT-portal setups. But there will be issues like adapting to other consumer-focused voice-driven home assistant platforms like Alexa, along with making it work with the widest range of home-automation devices.

Here, it is about implementing whatever common home-networking technology as part of assisted-living simply through using software to provide this kind of integration.

Ultrasound being used as a way to measure user proximity to gadgets

Article – From the horse’s mouth

Google Nest

How ultrasound sensing makes Nest displays more accessible {The Keyword blog post)

My Comments

Google is implementing in their Nest Hub smart-display products an automatic display-optimisation technology that is based on technology that has been used for a very long time.

Ultrasonic technology has been used in various ways by nature and humans to measure distance. In nature, bats and dolphins which don’t have good vision use this approach to “see” their way. It is used extensively in military and civillian marine applications to see what is underneath a boat or around a submarine and is also used as a common medical-imaging technique.

As well, in the late 1970s, Polaroid implemented ultrasound as part of their active autofocus system, which ended up as a feature for their value-priced and premium instant-picture cameras. Here, this was used to measure the distance between the camera and the subject in order to adjust the lens for proper focus. There were limitations associated with the technology like not being able to work when you photograph through a window due to the ultrasonic waves not passing through the glass.

But Google has implemented this technology as a way to adjust the display on their Nest Hub smart displays for distant or close operation. The front of a Google Nest Hub has an ultrasonic sensor that works in a similar way to what was used in a Polaroid auto-focus instant-picture camera.

But rather than the Polaroid setup being about using the distance measurement from the ultrasonic sensor to adjust a camera’s lens, this application adjusts the display according to the user’s distance from the Nest Hub. If you are distant from the Nest Hub, you would see reduced information but the key details appear in a larger typeface. Then if you come closer to the Nest Hub, you would see more detail but at a smaller typeface.

Nest Hub Directions display press picture courtesy of Google

The Google blog article described this as being suitable for older users and those of us who have limited vision. The fact that you have the ability to see key information in a large typeface at a distance can make the Nest Hub accessible to this user group. But others can’t see deeper information unless they are very close to the device.

End-user privacy is still assured thanks to the use of a low-resolution distance-measurement technology whose results are kept within the device. As well, there is a menu option within the Google Home app’s Device Settings page to enable or disable the feature.

At the moment, it is initially being used for timer and current-time display as well as displaying travel time and traffic conditions for a planned journey that you set up with Google Maps. But Google and other software developers who develop for the Google Home ecosystem will add distance-sensitive display functionality to more applications like appointments and alerts.

Some people could see this technology not just for optimising the readout on a smart display but could even be used to ascertain whether people are actually using these devices. This could then be used for such functionality like energy-saving behaviour where the display turns off if no-one’s near it.

But what Google has to do is to license out this technology to allow others to implement it it to other fixed-display-based devices. Here, it could become of more use to many who don’t go for a Google Nest Hub.

Amazon and Leading Technology Companies Announce the Voice Interoperability Initiative (Press Release)

My Comments

Amazon have instigated the Voice Interoperability Initiative which, at the moment, allows a hardware or software device to work with multiple compatible voice-driven AI assistants. It also includes the ability for someone to develop a voice-driven assistant platform that can serve a niche yet have it run on commonly-available smart-speaker hardware alongside a broad-based voice-driven assistant platform.

Freebox Delta press photo courtesy of Iliad (Free.fr)

Freebox Delta as an example of a European voice-driven home assistant that could support multiple voice assistant platforms

An example they called out was to run the Salesforce Einstein voice-driven assistant that works with Salesforce’s customer-relationship-management software on the Amazon Echo smart speaker alongside the Alexa voice assistant. Similarly, a person who lives in France and is taking advantage of the highly-competitive telecommunications and Internet landscape there by buying the Freebox Delta smart speaker / router and have it use Free.fr’s voice assistant platform or Amazon Alexa on that same device.

Microsoft, BMW, Free.fr, Baidu, Bose, Harman and Sony are behind this initiative while Google, Apple and Samsung are definitely absent. This is most likely because Google, Apple and Samsung have their own broad-based voice-driven assistant platforms that are part of their hardware or operating-system platforms with Apple placing more emphasis on vertically-integrating some of their products. It is although Samsung’s Android phones are set up to be able to work with their Bixby voice assistant or Google’s Assistant service.

Intel and Qualcomm are also behind this effort by offering silicon that provides the power to effectively understand the different wake words and direct a session’s focus towards a particular voice assistant.

The same hardware device or software gateway can recognise assistant-specific wake words and react to them on a session-specific basis. There will be the ability to assure customer privacy through measures like encrypted tunnelling for each assistant session along with an effort to be power-efficient which is important for battery-operated devices.

Personally I see this as an ability for companies to place emphasis on niche voice-assistant platforms like what Salesforce is doing with their Einstein product or Microsoft with its refocused Cortana product.  It can even make the concept of these voice assistants more relevant to the enterprise market and business customers.

Similarly, telcos and ISPs could create their own voice-driven assistants for use by their customers, typically with functionality that answers what they want out of the telco’s offerings. It can also extend to the hotel and allied sectors that wants to use voice-driven assistants for providing access to functions of benefit to hotel guests like room service, facility booking and knowledge about the local area. Let’s not forget vehicle builders who implement voice-driven assistants as part of their infotainment technology so that the drive has both hands on the wheel and eyes on the road.

This kind of offering can open up a market for the creation of “white-label” voice-assistant platforms that can be “branded” by their customers. As well, some of these assistants can be developed with a focus towards a local market’s needs like high proficiency in a local language and support for local values.

For hardware, the Amazon Voice Interoperability Initiative can open up paths for innovative devices. This can lead towards ideas like automotive applications, smart TVs, build-in use cases like intercom / entryphone or thermostat setups, software-only assistant gateways that work with computers or telephone systems amongst other things.

With the Amazon Voice Interoperability Alliance, there will be increased room for innovation in the voice-driven assistant sector.

Ambient Computing–a new trend

Article

Smart speakers like the Google Home are the baseline for the new concept of ambient computing

Lenovo see smart displays as a foundation for ambient computing | PC World

My Comments

A trend that is appearing in our online life is “ambient computing” or “ubiquitous computing”. This is where the use of computing technology is effective part of our daily lives without us having to do something specific about it.

One driver that is facilitating it is the use of voice-driven assistant technology like Apple’s Siri, Amazon’s Alexa, Google’s Assistant or Microsoft’s Cortana. It has manifested initially in mobile operating systems like Android or iOS but has come about more so with smart speakers of the Amazon Echo, Google Home or Apple HomePod kind along with Microsoft and Apple putting this functionality in to desktop operating systems like MacOS and Windows.

as are smart displays of the Lenovo Smart Display kind

As well, Amazon and Google have licensed out front-end software for their voice-driven home assistants so that third-party equipment manufacturers can integrate this functionality in their consumer-electronics products. It also includes the availability of devices that connect to larger-screen TVs or higher-quality sound systems to use them as display or audio surfaces for these voice-driven assistants, even simply just to play audio or video content pulled up at the command of the user.

Lenovo underscored this with their current Smart Display products and the up-and-coming Smart Display products including a Lenovo Yoga Smart Tab which was premiered at IFA 2019 in Berlin. These are based on the Google Home platform and they were underscoring the role of these displays in ambient computing.

Another key driving factor is the Internet of Things which may be seen in the home context as lights, appliances and other devices connected to the home network and Internet. It doesn’t matter whether they connect to the IP-based home network directly or via a “home hub” device. These work with the various voice-driven home-assistant platforms as sensors or controlled devices or, in some cases, alternate control surfaces.

It extends beyond the home through interaction with various building-wide or city-wide services that relate to energy use, transport, personal security amongst other things.

The other key driver that is highlighted is the use of distributed computing or “the cloud” where the data is processed or presented in a manner that is made available via the Internet on any device. It can also include online services that present information or content at your fingertips from anywhere in the world. In some cases, there is the use of data aggregation to create a wider picture of what is going on.

What this all adds up to is the concept of an “information butler” that responds with information or content as you need it. This is underscored with ambient or ubiquitous computing that is not just a Silicon Valley buzzword but a real concept.

What does the concept of ambient or ubiquitous computing underscore?

Here it is the use of information technology in a manner that blends in with your lifestyle rather than being a separate activity. You interact with one or more of the endpoints while you undertake a regular daily task and this can be about showing up information you need or setting up the environment for that activity. It relies less on active participation by the end-user.

Ambient computing is adaptive in that it fits in and adapts to your changing needs. It is also anticipatory because it can anticipate future needs like, for example, changing the heating setting to cope with a change in the weather. It also demonstrates context awareness by recognising users and the context of their activity.

But ambient computing still has its issues. One key issue that is called out frequently is end-user privacy including protection of minor children when users interact with these systems. An article published by Intel underscores this in the context of simplifying the management of our privacy wishes with the various devices and online services through the use of “agent” software.

This also relates to data security for the infrastructure along with data sovereignty (which country the data resides in) due to issues like information theft and use of information by foreign governments.

Similarly, allowing ambient-computing environments to determine activities like what content you enjoy can be of concern. This is more important because you may choose particular content based on your values and what others who have similar tastes and values recommend. It can also lead to avoiding addiction to content that can be socially harmful or enforcing the consumption of a particular kind of content upon people at the expense of other content.

Another factor that can creep up if common data-interchange standards aren’t implemented is the existence of data “silos”. This is where an ambient computing environment is limited to hardware and software provided by particular vendors. It can limit competition in the provision of these services which can restrict the ability to innovate when it comes to developing these systems further.

But what is now being seen as important for our online life is the trend towards ubiquitous ambient computing that simply is part of our lives.

You can manage your Google Home’s lighting and volume for night-time use

You can use the Google Home app to manage how your Google Home smart speaker works during the evening and night hours for a better night’s sleep

Manage volume and LED brightness with Night mode (Instruction sheet)

My Comments

Some of you may want to interact with a Google Home smart speaker during the wee hours of the day such as to ask for the time or weather. Or you may touch the device and work it as a night-light. But it can be too bright or loud at these times in a way that people can be woken up at odd hours. Here, some users have to adjust the volume to avoid this risk of disturbance.

But Google has a “Night Mode” feature that allows you to determine the maximum volume and device lighting brightness during times when you don’t want to be disturbed.

Here, you have to use the Google Home mobile-platform app on your smartphone or tablet. As well, your mobile device has be on the same logical network as the Google Home device, which would typically be the same Wi-Fi network when you are thinking of your home network.

When you open the Google Home app, tap on the gear-shape Settings icon and you will see the “Night Mode” setting in the list of settings. There is a toggle switch to enable or disable this mode, and when you enable this mode, the LEDs on the top of your Google Home device will dim while the maximum speaker volume will be softer.

There is an option to schedule the times and days of the week when the Night Mode feature will be active. This may be of importance if you want to make sure it comes in to play on weeknights for example.

There are settings to determine the maximum speaker volume and lighting brightness that will apply to your Google Home smart speaker while it is in the “Night Mode” condition.

The Do Not Disturb option on the Night Mode settings page mutes any notification or system sounds that your Google Home smart speaker makes. But timer or alarm signals will “break through” this setting so you don’t miss that extra alarm you set to wake you up so you can pick up that loved one from the airport as they come off that late flight.

But I am not sure whether these settings can be configured for individual devices or all of the devices bound to the same account. This may be of importance if you want to reduce the volume and lighting brightness on units installed in the bedrooms while one or more units installed in the common living areas are maintained at bright levels; or you want to maintain a common setting across your home.

A feature that can improve on this would be to have the LEDs on top of a Google Home device stay alight but at the maximum brightness to allow you to use the device as a night light. This is more so for those of us who would keep one of these devices in the corridor near the main bathroom or within that bathroom to serve as a “beacon” night-light to enable use of the bathroom at night.

At least Google has provided an option to allow the Google Home device family to work properly without disturbing other people’s sleep at night.

How to See and Delete Alexa’s Recordings of You | Tom’s Guide

You Can Now Tell Alexa To Delete Your Conversations | Lifehacker

My Comments

An issue that anyone with a voice-driven home assistant device will be wanting to have control of is what the device’s platform has recorded when they spoke to that device. It also includes the risk of your device being accidentally triggered by situations such as an utterance of the wake word in a recording or broadcast. A previous article that I have written describes how to achieve this kind of control with your Amazon Echo or similar Alexa-based device.

But Amazon have taken this further for the Alexa platform by allowing you to speak to your Alexa-based device to delete recordings left on the platform during particular time ranges.

How to enable this function

You have to use the Amazon Alexa app or Website to enable this feature but you don’t have to install another Alexa Skill in to your account for this purpose. Once you are logged in to your Amazon Alexa app or Website, enter the Settings section which would be brought up under a hamburger-shape “advanced-operations” menu.

Then you go to your “Alexa Account” option in that section and bring up the “Alexa Privacy” menu. Go to the “Review Voice History” screen and you will see the  “Enable Deletion By Voice” option that you can toggle on or off. Having this feature on will allow you to use the voice commands that will be listed below. When you enable it, you will see a warning that anyone with access to your Alexa-based devices will be able to delete what was said to the Alexa ecosystem.

Commands

“Alexa, delete everything I said today” will cause your Alexa-based device to delete anything you said to it from midnight (0:00) of the current day to the time you gave that instruction.

For greater control, Amazon will roll out this other command: “Amazon, delete what I just said”. This will delete what was last said to your Alexa device and can be of use when handling a nuisance-trigger situation for example.

Conclusion

I would see the other voice-driven assistant platforms provide the ability to delete what you said under your voice control as a user-enabled option. This will be more so as the light shines brightly on what the Silicon Valley establishment are up to with end-user data privacy amongst other issues like corporate governance.

The Amazon Echo will benefit from Amazon’s free music service

One of these is a free-to-end-user service option which is supported by audio advertising that plays in a similar manner to commercial free-to-air music radio.

Spotify had, for a long time, established its streaming-music service on a “freemium” model with an ad-supported basic service tier free to the end-user. This is alongside their Premium service tier which can be fully enjoyed on your mobile device or Spotify Connect endpoint audio devices and without advertising.

The advertising models included display advertising on the user interface along with radio-commercial-type audio ads at regular intervals. They also offer to marketers advertising ideas like sponsored playlists or sponsored listening sessions.

Now Amazon and Google are offering a free-music ad-supported streaming tier for their “online jukeboxes” but this will be limited to their smart-speaker platforms rather than a Web-based or mobile-based experience. There will also be a limited music offering available through this music tier.

The other is a premium streaming service that yields at least CD-grade audio fit to be played through that hi-fi system rather than an experience similar to FM radio.

TiDAL and Deezer based their music-streaming service on listeners who value high-quality sound for a long time. You may have heard music streamed from one or both of these services if you have recently attended a hi-fi show like any of the Chester Group hi-fi shows where I have heard TiDAL in action, or visited a boutique hi-fi or home-AV store.

Amazon aren’t taking this lightly and are offering the HD and Ultra HD service tiers which are the hi-fi-grade premium service tiers for their Amazon Music Unlimited streaming-music service. This is priced at US$15 per month with a view to undercut TiDAL and Deezer and is also targeted towards people who use Alexa-platform audio devices with their hi-fi system or use an Alexa-based network multiroom setup.

The Amazon service offers the high-quality service as two tiers – the HD one that is equivalent to CD quality and the Ultra HD one that is equivalent to “master quality”. These use the FLAC codec to trasfer the music to your equipment and you may find that the HD tier is similar to what you get if you are “ripping” a CD to FLAC files with, perhaps, Windows Media Player in Windows 10.  They are working with the record labels to license their music libraries to this service in order to have more high-grade content.

What is this to lead to

I see this opening up the floodgates for a highly-volatile streaming-music service market with companies wanting to cut in with entry-level free tiers driven by advertising or premium hi-fi-grade subscription tiers for those who value high-quality sound. Here, I would see at most of these companies running a three-tier music service for consumers – an ad-supported limited-content free service, a standard package with the whole library delivered ad-free and a premium package that has access to the whole library with CD-grade or master-grade audio.

There will be some factors that will allow each streaming-music service to differentiate themselves in a crowded market. They will become more important as a way to attract new subscribers or retain their existing subscriber base. It will also become important in encouraging people who have subscriptions with all of the services to focus their attention to a particular service.

One of these would be the quantity and quality of music playlists, especially curated playlists. Another would be the richness of information available to the user about the performers, composers, genres and other factors regarding the music library.

There will also be whether the music library contains underrepresented content and how much of this content is available to the users. This includes whether they offer a classical-music service with the expectations of such a service like composer-based searching.

Another issue that will show up is the provision of client-side support in standalone audio equipment so you aren’t running extra software on a computer or mobile device to get the music from that service to the speakers. This will also include having software for these services integrated in your car’s dashboard.

There will be the issue of what kind of partnerships the streaming-music service provider can have with the business community. It ranges from  “business music” service tiers with music properly licensed for public-performance on business premises to advertising and sponsorship arrangements like what Spotify has achieved.

As far as the creative team behind the music is concerned, a differentiation factor that will come about is how each streaming-music service renumerates these teams. It is whether they are the composers, arrangers, lyricists or music publishers behind the songs or the performers and record labels behind the recordings.

There will also be the issue of encouraging other vendors to tie-in streaming-music subscription as part of a package deal. This could be through an ISP or telco providing this service as part of an Internet or mobile-telephony service plan. Or buying a piece of equipment like an Internet radio could have you benefit from reduced subscription costs for a particular streaming-music service.

What I see of the online music-streaming market is something that will be very volatile and competitive.
