Staying Ahead with Advanced AI on Devices

June 8, 2017

Since the beginning, Sensory has been a pioneer in advancing AI technologies for consumer electronics. Not only did Sensory implement the first commercially successful speech recognition chip, but we also were first to bring biometrics to low cost chips, and speech recognition to Bluetooth devices. Perhaps what I am most proud of though, more than a decade ago Sensory introduced its TrulyHandsfree technology and showed the world that wakeup words could really work in real devices, getting around the false accept and false reject, and power consumption issues that had plagued the industry. No longer did speech recognition devices require button presses…and it caught on quickly!

Let me go on boasting because I think Sensory has a few more claims to fame… Do you think Apple developed the first “Hey Siri” wake word? Did Google develop the first “OK Google” wake word? What about “Hey Cortana”? I believe Sensory developed these initial wake words, some as demos and some shipped in real products (like the Motorola MotoX smartphone and certain glasses). Even third-party Alexa and Cortana products today are running Sensory technology to wake up the Alexa cloud service.

Sensory’s roots are in neural nets and machine learning. I know everyone does that today, but it was quite out of favor when Sensory used machine learning to create a neural net speech recognition system in the 1990’s and 2000’s.  Today everyone and their brother is doing deep learning (yeah that’s tongue in cheek because my brother is doing it too! (http://www.cs.colorado.edu/~mozer/index.php). And a lot of these deep learning companies are huge multi-billion-dollar business or extremely well-funded startups.

So, can Sensory stay ahead now and continuing pioneering innovation in AI now that everyone is using machine learning and doing AI? Of course, the answer is yes!

Sensory is now doing computer vision with convolutional neural nets. We are coming out with deep learning noise models to improve speech recognition performance and accuracy, and are working on small TTS systems using deep learning approaches that help them sound lifelike. And of course, we have efforts in biometrics and natural language that also use deep learning.

We are starting to combine a lot of technologies together to show that embedded systems can be quite powerful. And because we have been around longer and thought through most of these implementations years before others, we have a nice portfolio of over 3 dozen patents covering these embedded AI implementations. Hand in hand with Sensory’s improvements in AI software, companies like ARM, NVidia, Intel, Qualcomm and others are investing and improving upon neural net chips that can perform parallel processing for specialized AI functions, so the world will continue seeing better and better AI offerings on “the edge”.

Curious about the kind of on-device AI we can create when combining a bunch of our technologies together? So were we! That’s why we created this demo that showcases Sensory’s natural language speech recognition, chatbots, text-to-speech, avatar lip-sync and animation technologies. It’s our goal to integrate biometrics and computer vision into this demo in the months ahead:

Let me know what you think of that! If you are a potential customer and we sign an NDA, we would be happy to send you an APK of this demo so you can try it yourself!

Untethering virtual assistants from Wi-Fi

February 1, 2017

The hands-free personal assistant that you can wake on voice and talk to naturally has significantly gained popularity the last couple of years. This kind of technology made its debut not all that long ago as a feature of Motorola’s MotoX, a smartphone that had always-listening Moto Voice technology powered by Sensory’s TrulyHandsfree technology. Since then, the always-listening digital assistant quickly spread across mobile phones and PCs from several different brands, making phrases like, “Hey Siri,” “Okay Google,” and, “Hey Cortana,” commonplace.

Then, out of nowhere, Amazon successfully tried its hand at the personal assistant with the Echo, sporting a true natural language voice interface and Alexa cloud-based AI. It was initially marketed for music, but quickly expanded domain coverage to include weather, Q&A, recipes, and the ability to answer common questions. On top of that, Amazon also opened its platform up to third-party developers, allowing them to proliferate the skill sets available on the Alexa platform, with now more than 10,000 skills accessible to users. These skills allow Amazon’s Echo, Tap, and Dot, as well as the several new third-party Alexa-equipped products like Nucleus and Triby, to be used to access and control various IoT functions, from reading heart rates on Fitbits to ordering pizzas and controlling lights within the home.

Virtual Assistants coming to an Ear Near You!

January 5, 2017

Virtual handsfree assistants that you can talk to and that talk back have rapidly gained popularity. First, they arrived in mobile phones with Motorola’s MotoX that had an ‘always listening’ Moto Voice powered by Sensory’s TrulyHandsfree technology. The approach quickly spread across mobile phones and PCs to include Hey Siri, OK Google, and Hey Cortana.

Then Amazon took things to a whole new level with the Echo using Alexa. A true voice interface emerged, initially for music but quickly expanding domain coverage to include weather, Q&A, recipes, and the most common queries. On top of that, Amazon took a unique approach by enabling 3rd parties to develop “skills” that now number over 6000! These skills allow Amazon’s Echo line (with Tap, Dot) and 3rd Party Alexa equipped products (like Nucleus and Triby) to be used to control various functions, from reading heartrates on Fitbits to ordering Pizzas and controlling lights.

Until recently, handsfree assistants required a certain minimum power capability to really be always on and listening. Additionally, the hearable market segment including fitness headsets, hearing aids, stereo headsets and other Bluetooth devices needed to use touch control because of their power limitations. Also, Amazons Alexa had required WIFI communications so you could sit on your couch talking to your Echo and query Fitbit information, but you couldn’t go out on a run and ask Alexa what your heartrate was.

All this is changing now with Sensory’s VoiceGenie!

The VoiceGenie runs an embedded recognizer in a low power mode. Initially this is on a Qualcomm/CSR Bluetooth chip, but could be expanded to other platforms. Sensory has taken an SBC music decoder and intertwined a speech recognition system, so that the Bluetooth device can recognize speech while music is playing.

The VoiceGenie is on and listening for 2 keywords:
Alexa – this enables Alexa “On the Go” through a cellphone rather than requiring WiFi
VoiceGenie – this provides access to all the Bluetooth Device and Handset Device features

For example, a Bluetooth headset’s volume, pairing, battery strength, or connection status can only be controlled by the device itself, so VoiceGenie handles those controls without touching required. VoiceGenie can also read incoming callers’ names and ask the user if they want to answer or ignore. VoiceGenie can call up the phone’s assistant, like Google Assistant or Siri or Cortana, to ask by voice for a call to be made or a song to be played.
By saying Alexa, the user gets access to a mobile Alexa ‘On the Go’, so any of the Alexa skills can be utilized while out and about, whether hiking or running!

Some of the important facts behind the new VoiceGenie include:

  • VoiceGenie is a platform for VoiceAssistants to be used Handsfree on tiny devices
  • VoiceGenie enables Alexa for a whole new range of portable products
  • VoiceGenie enables a movement towards invisible assistants that are with you all the time and help you in your daily lives

This third point is perhaps the least understood, yet the most important. People want a personalized assistant that knows them, keeps their secrets safe, and helps them in their daily lives. This help can be accessing information or controlling your environment. It’s very difficult to accomplish this for privacy and power reasons in a cloud powered environment. There needs to be embedded intelligence. It needs to be low power. VoiceGenie is that low powered voice assistant.

Assistant vs Alexa: 8 things not discussed (enough)

October 14, 2016

I watched Sundar and Rick and the team at Google announce all the great new products from Google. I’ve read a few reviews and comparisons with Alexa/Assistant and Echo/Home, but it struck me that there’s quite an overlap in the reports I’m reading and some of the more interesting things aren’t being discussed.

Who (or what) is really listening to your conversation

June 22, 2016

I’ve written a series of blogs about consumer devices with speech recognition, like Amazon Echo. I mentioned that everyone is getting into the “always listening” game (Alexa, OK Google, Hey Siri, Hi Galaxy, Assistant, Hey Cortana, OK Hound, etc.), and I’ve explained that privacy concerns attempt to be addressed by putting the “always listening” mode on the device, rather than in the cloud.

IoT Roadshow with Open Systems Media

May 6, 2016

Rich Nass and Barbara Quinlan from Open Systems Media visited Sensory on their “IoT Roadshow”.

IoT is a very interesting area. About 10 years ago we saw voice controlled IoT on the way, and we started calling the market SCIDs – Speech Controlled Internet Devices. I like IoT better, it’s certainly a more popular name for the segment! ;-)

I started our meeting off by talking about Sensory’s three products – TrulyHandsfree Voice Control, TrulySecure Authentication, and TrulyNatural large vocabulary embedded speech recognition.

Although TrulyHandsfree is best known for its “always on” capabilities, ideal for listening for key phrases (like OK Google, Hey Cortana, and Alexa), it can be used a ton of other ways. One of them is for hands-free photo taking, so no selfie stick is required. To demonstrate, I put my camera on the table and took pictures of Barbara and Rich.  (Normally I might have joined the pictures, but their healthy hair, naturally good looks, and formal attire was too outclassing for my participation).

There’s a lot of hype about IoT and Wearables and I’m a big believer in both. That said, I think Amazon’s Echo is the perfect example of a revolutionary product that showcases the use of speech recognition in the IoT space and am looking forward to some innovative uses of speech in Wearables!

Here’s the article they wrote on their visit to Sensory and an impromptu video showing TrulyNatural performing on-device navigation, as well as a demo of TrulySecure via our AppLock Face/Voice Recognition app.

IoT Roadshow, Santa Clara – Sensory: Look ma, no hands!

Rich Nass, Embedded Computing Brand Director

If you’re an IoT device that requires hands-free operation, check out Sensory, just like I did while I was OpenSystems Media’s IoT Roadshow. Sensory’s technology worked flawlessly running through the demo, as you can see in the video. We ran through two different products, one for input and one for security.

TrulyHandsfree 4.0… Maintaining the big lead!

August 6, 2015

We first came out with TrulyHandsfree about five years ago. I remember talking to speech tech executives at MobileVoice as well as other industry tradeshows, and when talking about always-on hands-free voice control, everybody said it couldn’t be done. Many had attempted it, but their offerings suffered from too many false fires, or not working in noise, or consuming too much power to be always listening. Seems that everyone thought a button was necessary to be usable!

In fact, I remember the irony of being on an automotive panel, and giving a presentation about how we’ve eliminated the need for a trigger button, while the guy from Microsoft presented on the same panel the importance of where to put the trigger button in the car.

Now, five years later, voice activation is the norm… we see it all over the place with OK Google, Hey Siri, Hey Cortana, Alexa, Hey Jibo, and of course if you’ve been watching Sensory’s demos over the years, Hello BlueGenie!

Sensory pioneered the button free, touch free, always-on voice trigger approach with TrulyHandsfree 1.0 using a unique, patented keyword spotting technology we developed in-house– and from its inception, it was highly robust to noise and it was ultra-low power. Over the years we have ported it to dozens of platforms, Including DSP/MCU IP cores from ARM, Cadence, CEVA, NXP CoolFlux, Synopsys and Verisilicon, as well as for integrated circuits from Audience, Avnera, Cirrus Logic, Conexant, DSPG, Fortemedia, Intel, Invensense, NXP, Qualcomm, QuickLogic, Realtek, STMicroelectronics, TI and Yamaha.

This vast platform compatibility has allowed us to work with numerous OEMs to ship TrulyHandsfree in over a billion products!

Sensory didn’t just innovate a novel keyword spotting approach, we’ve continually improved it by adding features like speaker verification and user defined triggers. Working with partners, we lowered the draw on the battery to less than 1mA, and Sensory introduced hardware and software IP to enable ultra-low-power voice wakeup of TrulyHandsfree. All the while, our accuracy has remained the best in the industry for voice wakeup.

We believe the bigger, more capable companies trying to make voice triggers have been forced to use deep learning speech techniques to try and catch up with Sensory in the accuracy department. They have yet to catch up, but they have grown their products to a very usable accuracy level, through deep learning, but lost much of the advantages of small footprint and low power in the process.

Sensory has been architecting solutions for neural nets in consumer electronics since we opened the doors more than 20 years ago. With TrulyHandsfree 4.0 we are applying deep learning to improve accuracy even further, pushing the technology even more ahead of all other approaches, yet enabling an architecture that has the ability to remain small and ultra-low power. We are enabling new feature extraction approaches, as well as improved training in reverb and echo. The end result is a 60-80% boost in what was already considered industry-leading accuracy.

I can’t wait for TrulyHandsfree 5.0…we have been working on it in parallel with 4.0, and although it’s still a long ways off, I am confident we will make the same massive improvements in speaker verification with 5.0 that we are doing for speech recognition in 4.0! Once again further advancing the state of the art in embedded speech technologies!
