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.

Speaking the language of the voice assistant

June 17, 2016

Hey Siri, Cortana, Google, Assistant, Alexa, BlueGenie, Hound, Galaxy, Ivee, Samantha, Jarvis, or any other voice-recognition assistant out there.

Now that Google and Apple have announced that they’ll be following Amazon into the home far-field voice assistant business, I’m wondering how many things in my home will always be on, listening for voice wakeup phrases. In addition, how will they work together (if at all). Let’s look at some possible alternatives:

Google Assistant vs. Amazon’s Alexa

June 15, 2016

“Credit to the team at Amazon for creating a lot of excitement in this space,” Google CEO Sundar Pichai. He made this comment during his Google I/O speech last week when introducing Google’s new voice-controlled home speaker, Google Home which offers a similar sounding description to Amazon’s Echo. Many interpreted this as a “thanks for getting it started, now we’ll take over,” kind of comment.

Google has always been somewhat marketing challenged in naming its voice assistant. Everyone knows Apple has Siri, Microsoft has Cortana, and Amazon has Alexa. But what is Google’s voice assistant called?

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!

Touch-less Control Wins!

June 9, 2014

I still subscribe to the San Jose Mercury News, as they do a good job of tech business reporting. One of my favorite Mercury News writers is a true critic in the literary sense of the term, Troy Wolverton. Troy rarely raves and is typically critical, but in a smart, logical, and unemotional way.

A few days back he started writing about Microsoft’s  Cortana and said “Watch out Siri, someone wants your job.”

I was eager to read his review of Cortana this morning and in particular his comparison with Siri. He ended up giving it a 7/10, and concluding Siri was still ahead. What I thought was most interesting though was that in his final summary, he compared three products and three assistants based on the ease of calling up each of those assistants:

  • Cortana – required two touch steps to activate the personal voice assistant
  • Siri – required one touch step to activate the personal voice assistant
  • MotoX – The best, because you can just start talking with the keyword phrase “OK Google Now” making a TrulyHandsfree experience!!

Motorola is Sensory’s customer, and I am happy to read that Troy gets it and considers this front end activation an important metric in comparing personal assistants!
