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!

Sensory Talks AI and Speech Recognition With Popular Science Radio Host Alan Taylor

Sensory’s CEO, Todd Mozer joined Alan Taylor, host of Popular Science Radio, in a fun discussion about artificial intelligence, Sensory’s involvement with the Jibo robot development team, and also gave the show’s listeners a look into the past 20 years of speech recognition. Todd and Alan additionally discussed some of the latest advancements in speech technology, and Todd provided an update on Sensory’s most recent achievements in the field of speech recognition as well as a brief look into what the future holds.

Ever wondered how accurate the science of the Big Bang Theory TV series is? Curious about how well speech recognition technology and robots are advancing? We interview two great minds to probe for these answers

I Love Robots!

July 31, 2014

Yeah, I grew up in an era of watching robots on TV and in the movies, and reading about them in books and comic strips. They were and still are a part of our media culture. My goal in life has been to live in a Jetsons-like world! Well, not really, but I do have a film slide of Rosie the Maid up on my wall, and the mod, Googie, mid-century future style from the Jetsons is definitely my style.

It’s been fun at Sensory to be part of a robot revolution in toys. We have put speech technologies into over 50 robotic creatures from dolls to strange new alien things like Furby. When Aibo first shipped, we had half a dozen companies come to us with awesome designs for new low cost robotic dogs that could respond to their masters’ voices!

Here’s a fun realistic looking robot dog – Scamps.  Sensory was in this a few years ago, and it seems to be enjoying a huge comeback in 2014.

More recently we were in Intel’s “Jarvis” headset…When we first created the Jarvis trigger, I didn’t get the name. Then I saw the movie Ironman! :-)

Sensory has designed a lot of robotic technologies beyond speech recognition and synthesis. We have platforms such as sound sourcing, where a robot with two mics can locate the speaker through triangulation. We have sonic networking as a low cost wireless protocol so robots can take commands from TV commercials or YouTube videos or even other robots. We even have made lip synchronization approaches and pitch detection technologies so robots can mimic their owners in a fun and playful way.

The rise of robotic vacuum and window cleaners and non-toy robotic applications is really Neato (yeah that’s a pun!) Of course there have been a lot of beer delivery home robots over the years too, but none of them are making it into the mainstream.

The magic however has not yet really hit, because I want the fun, playfulness, and interactivity of the toys but with utility added in, so it really is more like the Jetsons or Lost in Space.

Jibo is a new robot that might foot this bill, and it seems that I’m not the only one that likes the concept,  as it is getting pretty close to being one of the Top 10 funded Indiegogo campaigns of all time!
