Raising the IQ of Multiroom Smart Speakers

February 13, 2018

The Tech

At CES this year, many products on the show floor, from microwaves to automobiles, had either Alexa or Google Assistant (or both!) built in. And from what we saw, multiroom, Wi-Fi speakers were no exception. Since Amazon unveiled their flagship voice-activated smart speaker, Echo, in 2014, the audio industry has been drastically shaken. Although they don’t generally produce the best sound quality, smart speakers have become hugely popular. And now, many smart speakers are gaining hi-res audio abilities, like Google Home Max and Apple’s HomePod. And that’s got audio manufacturers worried. In a market dominated by smart speakers (in addition to the roll-out of smart speakers with enhanced audio abilities) CE companies have no choice but “to stay relevant in a Wi-Fi speaker market dominated by Amazon- and Google-branded smart speakers” by designing products that “feature microphones to detect voice commands and come with either Amazon Alexa or Google Assistant built in” (Sound and Vision).

While most audio manufacturers begin to launch multiroom Wi-Fi smart speakers that either incorporate or compete with Google and Amazon’s technology, here are a few key concepts to keep in mind:

Buffering Bummer

Most popular wireless speakers run on conventional Wi-Fi protocols which have to queue the data. This means that it takes several seconds for the first song to fill the buffer before it begins to play. While the first song plays, the system is already buffering the next song to minimize gaps. This is fine until you change the queue before the system can re-buffer. This certainly poses a problem for folks who want to use these wireless, smart speakers in a multiroom set up. Enter Real-Time Packet Management (RPM): the Blackfire solution to buffering. RPM uses a special multipoint, real-time feedback signal from each speaker to monitor the effects of noise on the audio data stream, which allows a much shorter queue and much less buffering.

Get In Sync

Regardless of how “smart” a Wi-Fi speaker is, problems will always arise when it comes to synchronizing multiple speakers in a multiroom set up. Problems facing a standard method of synchronization include: 1) performance that is tied to the performance of the network environment and 2) the more devices you have on a given network, the slower it runs, producing an extended lag between speakers and between your TV and the speakers – even total dropouts. Traffic Independant Synchronization (TIS) is Blackfire’s patented synchronization technology that can be used to sync any number of wireless devices, from multi speaker 5.1 audio systems, stereo systems, smart speakers, and even your entire home theater. Blackfire’s TIS technology always maintains latency between audio and video pairings and among the speakers themselves. And with TIS, the sync of the speakers will remain undisturbed by heavy network traffic.

Interfere Interference

Wireless, multi-speaker systems that use conventional Wi-Fi protocols are more susceptible to interference and heavy network traffic, which causes music to break up and for speakers to go out of sync. Dynamic Stream Balancing (DSB) is the way Blackfire makes the best use of the available Wi-Fi bandwidth. DSB monitors special multipoint, real-time feedback signals from each speaker to identify the effect of noise on the audio data stream. By precisely identifying which packets are statistically most likely to be affected, DSB uses the available Wi-Fi bandwidth to selectively, and predictively, resend data to the most vulnerable speaker before interference can cause any audible drop out.

The Blackfire Realtime Entertainment Distribution (RED) framework

Combining individual entertainment systems to work together (to create a truly connected smart home) is non trivial – it requires precise synchronization, low latency for lip sync and a general reliability over standard Wi-Fi (the best and most commonly used communication protocol for the home.) With The Blackfire Realtime Entertainment Distribution (RED) framework embedded into wireless smart speakers, users can finally enjoy a truly connected home. With voice commands, you can ask any Blackfire enabled device to play music, wirelessly and synchronously throughout the home, in groups, and on multiple devices. The Blackfire RED framework also supports low latency and multi-channel, which other wireless solutions do not.

Voice service solutions require a high performance, multi-room solution like the Blackfire RED framework, which can allow multiple devices to respond to voice commands, simultaneously, and can be integrated into a broad spectrum of high quality voice service applications.

The Blackfire RED framework enhances the performance of smart speakers and does what no other solution has done before. Our partners have already stepped into the future, leveraging Blackfire’s technology in their products. Now is your chance, too. Join the Blackfire revolution today.

Smart Speakers are for More Than Just Music

As smart speakers like the Amazon Echo and Google Home gain popularity, users are discovering more and more use cases for the technology in their homes. Besides the obvious music listening, what else are smart speaker owners using the technology for? The answer may (not) surprise you.

NPR and Edison Research conducted a study called The Smart Audio Report, which was based on a national online survey of 1,620 American adults. Out of the 800 respondents who said that they owned at least one smart speaker, 709 had an Alexa-enabled device, 160 owned a Google Home, and 69 owned both. No surprises, Amazon is dominating the smart speaker market.

52% of smart speaker owners responded that they keep their primary smart speaker in the living room, with the kitchen being the next highest placement for the smart speaker at 24%. This indicates that the living room is still being used as the main entertainment space, even as technology changes over time. Therefore, CE manufacturers should still view the living room as the epicenter for home entertainment systems. In terms of whole-home entertainment systems such as wireless speakers, the living room serves as great placement for a central hub that can control wireless speakers positioned throughout the house.

If you don’t have a smart speaker yet, you may be asking yourself, what’s the draw? What’s the main reason for even wanting a smart speaker in the first place? According to the report, respondents did not list listening to music as their number one reason for wanting a smart speaker, but rather, the top reason was to have the ability to ask questions or look up information without needing to type it into a phone or computer. This is pretty big news in favor of expanding voice control technology across various entertainment and service devices. Currently, we live in a tactile, app-based technological age: the modern smartphone was designed for viewing, touching, and engaging with a multitude of apps. But that may shift considerably within the next few years. Even though voice AI and voice control are still in their infancy, this study proves that many people want the ability to interact with their devices through their voice.

To the delight of Amazon, surely, 57% of respondents indicated that they have ordered an item through their smart speaker. Considering that retail is the driving force behind smart home innovations like Amazon’s Echo smart speakers powered by their voice AI, Alexa, we consider this a huge win for Amazon.

Overall, the study found that all types of smart speaker users (ranging from “heavy,” “medium,” and “light”), use their voice activated smart speakers regularly to play music, find out the weather, ask general questions, and set timers or alarms. As popularity for smart speakers increase, functionality will as well, and the smart speaker will likely become the central hub for the smart home of the future.

Improving the Smart Home Hub

It’s a challenge for smart home owners to gather all of their devices together under one simple, straightforward interface, but smart home hubs promise an easy way to bring isolated smart devices together. There are many smart home hubs out there, some of which now serve multiple purposes: the Amazon Echo is both a smart home hub and a voice activated smart speaker, while the Samsung Connect Home doubles as a router. When choosing a smart home hub, users tend to consider variables such as compatibility to their current smart home devices, ease of use, and unique features (such as voice control) to help them decide which hub is right for them. But how can smart home hub manufacturers help meet the demand of their users and ensure the technology’s longevity in the marketplace? And how can consumer electronics manufacturers help bridge the islands that pervade smart home entertainment and create hub-friendly solutions?

Before the advent of smart speakers, the best reason to invest in a smart home hub was to unify multiple communication protocols under one platform. Smart home hubs are designed to work across many different wireless standards, including Wi-Fi, Zigbee, Z-Wave, and Bluetooth. So if you have devices that work on different standards, a hub will most likely allow you to control them all from one centralized location, i.e., the hub’s app (note: not all smart home hubs work with every smart home device). But today, is this still enough of reason to spend upwards of hundreds of dollars on a hub? To most, the answer is ‘no.’ In a CNET article titled: “The only way to save the smart home hub is to kill it,” contributor David Priest contends that “folding the signal translation and automation capabilities of a hub into another essential device that people already buy — be it a router, TV or perhaps even security camera –…moves standalone hubs out of the middleman position in the smart home. As the market continues to develop, customers will be less inclined to spend over $100 on a device that does nothing in and of itself besides helping two other devices communicate…the smart home hub will only survive if it’s reincarnated as something more.”

That’s why products like the Amazon Echo, Google Home, and Samsung Connect Home are so appealing to consumers: they do so much more than just link up your solitary smart devices. Launched in 2014, the Echo was the first mass market voice-controlled smart home hub, and since then, other companies like Google and Apple have jumped on the bandwagon. Besides it being able to connect to a plethora of smart devices (with more and more being added each quarter) which you can control through voice commands, the Echo is also an excellent standalone smart speaker, which makes it that much more appealing to consumers. What traditional smart home hubs do really well (that devices like an Echo or Google Home do not) is offer better scheduling and automation controls, so there are some reasons why a user may opt for something other than an Echo or HomePod. But in order to stay relevant, smart home hub manufacturers must follow the “more bang for your buck” model and combine unique features (such as voice control or even just a first-class app) with the traditional hub.

But what about from the consumer electronics end – the entertainment devices users want to connect to a central hub, such as wireless speakers? Combining individual entertainment systems to work together to create a truly connected smart home is non trivial – it requires precise synchronization, low latency for lip sync and a general reliability over standard Wi-Fi (the best and most commonly used communication protocol for the home.) Something like this hasn’t been done before – until now.

Blackfire Research is making the smart home smarter by helping consumer electronics manufacturers get their products off isolated entertainment islands and create hub-friendly solutions. Our revolutionary new protocol, The Blackfire Realtime Entertainment Distribution (RED) framework, allows users to mix and match entertainment devices – from multiple brands that are Blackfire enabled – to create a whole home entertainment system. With the Blackfire RED framework embedded in wireless speakers and the smart home’s voice-activated smart speaker (such as an Echo or a Dot), users can finally enjoy a truly connected home. With Alexa, you can ask any Blackfire enabled device to play music, wirelessly and synchronously throughout the home, in groups and on multiple devices. The Blackfire RED framework also supports low latency and multi-channel, which other wireless solutions do not.

The Blackfire RED framework is the most synchronous, reliable, and cost effective wireless solution on the market. Voice service solutions require a high performance, multi-room solution like the Blackfire RED framework, which can allow multiple devices to respond to voice commands, simultaneously, and can be integrated into a broad spectrum of high quality voice service applications.

The Blackfire RED framework enhances the smart home hub and does what no other solution has done before. Harman Kardon, Pioneer, and Onkyo have stepped into the future by leveraging Blackfire’s technology in over 100 new products this year alone. Now is your chance. Join the Blackfire Revolution today.

Alexa, is this all just a fad?

According to a recent article in The Wall Street Journal, more and more electronic manufacturers in China, like Alibaba, are getting involved in the AI smart speaker market, fueling its growth and begging the question: are talking speakers just a passing tech fad or are they here to stay?

In the US, tech giants, Amazon and Google, dominate the AI smart speaker space with their Alexa-enabled Echo and Echo Dot; and the Google Assistant-powered Google Home, respectively. As the Wall Street Journal notes: “tech giants [and] consumer electronics makers…all see voice-activated products as the gateway to a future where platforms animated by artificial intelligence will power homes, cars and offices. To some, this first wave in the AI revolution already looks frothy.” And that sentiment is seen played out in Apple’s recently announced Siri-enabled smart speaker, HomePod. A late addition to the fray, the HomePod will be available to consumers by December 2017, and it’s capabilities are an indication that it’s entering a rapidly maturing market.

The HomePod’s positioning is geared more towards smart acoustics than smart AI. Yes, users can control the speaker via Siri voice activation, but the majority of the speaker’s smart functions are audio or music related. One reason for investing heavily in smart acoustics is because, so far, smart speakers don’t sound that great. To differentiate themselves from the pack, Apple is attempting to offer an alternative smart speaker for audiophiles, music enthusiasts and Apple loyalists. Will this positioning work? Perhaps. But the fact remains – the HomePod is merely a lateral move in terms of smart home advancement.

For a new technology, innovation in the smart speaker sphere has been fairly stagnant (for more on this, read my previous blog post “A Clear Path for Voice Control”), and many people who were looking to Apple as a game changer in the field were left mostly underwhelmed by the unveiling of HomePod. Therefore, the direction Apple took with it’s smart speaker only adds to the feeling that the smart speaker bubble is about ready to burst, since we’re still getting variations of “more of the same.”

Amazon, on the other hand, has spent this year rolling out AI smart devices that are not just music speakers, though this fragmentation of the Smart-AI market is already looking too niche for sustained growth. Products such as the Amazon Echo Show (an Echo with video capabilities) and the Amazon Echo Look (an Echo with a camera so you can take pictures of your outfits to log in your “virtual closet” and get fashion advice from “experts”) seem more like placeholder products than fully thought-through use-cases. Amazon knows that the design and UI of the Show are flawed (for example, there’s no way to decline a video call, so friends or relatives with a Show can pop into yours at any moment), and Amazon knows that the Look is about as useful as, what’s it called? Oh yeah, a mirror. But Amazon also knows that AI technology is in a moment of stasis, and between now and the next major smart home breakthrough, they are doing everything they can to keep the ball rolling (and capture an exuberant amount of data about its customers).

So, are AI smart speakers just a fad? Is the bubble about to burst? Perhaps the answer to that is a soft “no.” As smart speakers stand today, the use cases for it are fairly narrow, but that doesn’t mean more smart home innovation won’t branch out from it, as many see the smart speaker as playing a pivotal role in the future smart home. There’s a lot that can be done with an AI smart speaker in the future, but the technology needs to catch up to the possibilities.
