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.
Let’s now look deeper into the “always listening” approaches and compare some of the different methods and platforms available for embedded triggers.
There are a few basic approaches for running embedded voice wakeup triggers:
First, is running on an embedded DSP, microprocessor, and/or smart microphones. I like to think of this as a “deeply embedded: approach as opposed to running embedded on the operating system (OS). Knowles recently announced a design with a smart mike that provides low-power wake up assistance.
Many leading chip companies have small DSPs that are enabled for “wake up word” detection. These vendors include Audience, Avnera, Cirrus Logic, Conexant, DSPG, Fortemedia, Intel, InvenSense, NXP, Qualcomm, QuickLogic, Realtek, STMicroelectronics, TI, and Yamaha. Many of these companies combine noise suppression or acoustic echo cancellation to make these chips add value beyond speech recognition. Quicklogic recently announced availability of an “always listening” sensor fusion hub, the EOS S3, which lets the sensor listen while consuming very little power.
Next is DSP IP availability. The concept of low-power voice wakeup has gotten so popular amongst processor vendors that the leading DSP/MCU IP cores from ARM, Cadence, CEVA, NXP CoolFlux, Synopsys, and Verisilicon all offer this capability, and some even offer special versions targeting this function.
Running on an embedded OS is another option. Bigger systems like Android, Windows, or Linux can also run voice wake-up triggers. The bigger systems might not be so applicable for battery-operated devices, but they offer the advantage of being able to implement larger and more powerful voice models that can improve accuracy. The DSPs and MCUs might run a 50-kbyte trigger at 1 mA, while bigger systems can cut error rates in half by increasing models to hundreds of megabytes and power consumption to hundreds of milliamps. Apple used this approach in its initial implementation of Siri, thus explaining why the iPhone needed to be plugged in to be “always listening.”
Finally, one can try combinations and multi-level approaches. Some companies are implementing low-power wake-up engines that look to a more powerful system when woken up to confirm its accuracy. This can be done on the device itself or in the cloud. This approach works well for more complex uses of speech technology like speaker verification or identification, where the DSPs are often crippled in performance and a larger system can implement a more state of the art approach. It’s basically getting the accuracy of bigger models and systems, while lowering power consumption by running a less accurate and smaller wakeup system first.
A variant of this approach is accomplished with a low-power speech detection block acting as an always listening front-end, that then wakes up the deeply embedded recognition. Some companies have erred by using traditional speech-detection blocks that work fine for starting a recording of a sentence (like an answering machine), but fail when the job is to recognize a single word, where losing 100 ms can have a huge effect on accuracy. Sensory has developed a very low power hardware sound-detection block that runs on systems like the Knowles mike and Quicklogic sensor hub.

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:
Co-existence. We’re heading down a path where we as consumers will have multiple devices on and listening in our homes and each device will respond to its name when spoken to. This works well with my family; we just talk to each other, and if we need to, we use each other’s names to differentiate. I can have friends and family over or even a big party, and it doesn’t become problematic calling different people by different names.
The issue for household computer assistants all being on simultaneously is that false fires will grow in direct proportion to the number of devices on and listening. With Amazon’s Echo, I get a false fire about every other day, and Alexa does a great job of listening to what I say after the false fire and ignoring if it doesn’t seem to be an intended command. It’s actually the best performing system I’ve used and the fact that its starts playing music or talking every other week is a testament to what a good job they have done. However, interrupting my family every other week is not good enough. And if I have five always-listening devices interrupting us 10 times a month, that becomes unacceptable. And if they don’t do as good a job as Alexa, and interrupt more frequently, it becomes quite problematic.
Functional winners. Maybe each device could own a functional category. For example, all my music systems could use Alexa, my TV’s use Hi Galaxy, and all appliances are Bosch. Then I’d have less “names” to call out to and there would be some big benefits: 1) The devices using the same trigger phrase could communicate and compare what they heard to improve performance; 2) More relevant data could be collected on the specific usage models, thus further improving performance; and 3) With less names to call out, I’d have fewer false fires. Of course, this would force me as a consumer to decide on certain brands to stick to in certain categories.
Winner take all. Amazon is adopting a multi-pronged strategy of developing its own products (Echo, Dot, Tap, etc.) and also letting its products control other products. In addition, Amazon is offering the backend Alexa voice service to independent product developers. It’s unclear whether competitors will follow suit, but one thing is clear—the big guys want to own the home, not share it.
Amazon has a nice lead as it gets other products to be controlled by Echo. The company even launched an investment fund to spur more startups writing to Alexa. Consumers might choose an assistant we like (and we think performs well) and just stick with that across the household. The more we share with that assistant, the better it knows us, and the better it serves us. This knowledge base could carry across products and make our lives easier.
Just Talk. In the “co-existence” case previously mentioned, there six people in my household, so it can be a busy place. But when I speak to someone, I don’t always start with their name. In fact, I usually don’t. If there’s just one other person in the room, it’s obvious who I’m speaking to. If there are multiple people in the room, I tend to look at or gesture toward the person I’m addressing. This is more natural than speaking their name.
An “always listening” device should have other sensors to know things like how many people are in the room, where they’re standing and looking at, how they’re gesturing, and so on. These are the subconscious cues humans use to know who is talking to us, and our devices would be smarter and more capable if they could do it.

“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? Is it Google Voice, Google Now, OK Google, Voice Actions? Even those of us in the speech industry have found Google’s branding to be confusing. Maybe they’re clearing that up now by calling their assistant “Google Assistant.” Maybe that’s the Google way of admitting it’s an assistant without admitting they were wrong by not giving it a human sounding name.
The combination of the early announcement of Google Home and Google Assistant has caused some to comment that Amazon has BIG competition at best, and at worst, Amazon’s Alexa is in BIG trouble.
I thought I’d point out a few good reasons why Amazon is in pretty good shape:
Of course, Amazon has its challenges as well, but I’ll leave that for another blog.

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.
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.

Todd Mozer’s interview with Martin Wasserman on FutureTalk
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!

I was at the Mobile Voice Conference last week and was on a keynote panel with Adam Cheyer (Siri, Viv, etc.) and Phil Gray (Interactions) with Bill Meisel moderating. One of Bills questions was about the best speech products, and of course there was a lot of banter about Siri, Cortana, and Voice Actions (or GoogleNow as it’s often referred to). When it was my turn to chime in I spoke about Amazon’s Echo, and heaped lots of praise on it. I had done a bit of testing on it before the conference but I didn’t own one. I decided to buy one from Ebay since Amazon didn’t seem to ever get around to selling me one. It arrived yesterday.
Here are some miscellaneous thoughts:
OK, Amazon… here’s my free advice (admittedly self-serving but nevertheless accurate):
