An interesting blog post (from PC World) came out following Apple’s iPhone 4s intro with Siri. I think everyone knows what Siri is…it’s the Apple acquisition that has turned into a big part of the Apple user experience. Siri technology allows a user to not only search but control various aspects of a smartphone by voice in a “natural language” manner.
The blog post depicts a looming showdown between Sensory and Apple’s Siri. It is quite kind to Sensory, pointing out our near-flawless performance in noise and how TrulyHandsfree™ does not require button presses. While those points are true, Sensory is certainly NOT a competitor to Siri. We do partner with companies like Vlingo that might be considered a Siri competitor, but Sensory’s TrulyHandsfree is just the first part of a multi-stage process for creating a true Voice User Interface.
Here is the basic process:
It’s just that first step that Sensory does better than anyone else. However, it’s an important step that requires a few critical characteristics:
Companies like Nuance, Vlingo, Google and Microsoft are pretty good at the second step, which is a more powerful (often cloud-based) recognition system.
The third step “Understanding Meaning” is what the original Siri was all about. This was an AI component developed under DARPA funding at SRI and later spun off and acquired by Apple. Apple is rumored to be using Nuance as the “Step 2” in Siri.
Vlingo does a really nice job of implementing Steps 1-3 (using Sensory as its partner for Step 1.) I’m sure Google, Microsoft, Apple and Nuance all have efforts underway in the area of AI and natural language understanding. It’s really not that different than what they have needed for text-based “meaning” recognition during traditional searches.
The SEARCH in Step 4 is done via typical search engines (Google, Microsoft, Apple) and I’d guess Vlingo and other independent players (are there any still around???) have developed partnerships in these areas.
Step 5 is basically a good quality TTS engine. Providers like Nuance, Ivona, ATT, NeoSpeech, and Acapella all have nice TTS engines, and I believe Apple, Microsoft and Google all have in-house solutions as well!
The important point in comparing Sensory’s technology is that we provide the logical entryway to a successful Voice User Interface experience–with a lightning-fast voice trigger that replaces tactile button presses. It is a given that noise immunity and extremely high accuracy are also required, and Trulyhandsfree accomplishes this without requiring a prohibitive amount of power to function reliably and consistently.
AND…while we appreciate the comparison to the most profitable company on the planet, we’d like to focus on what we do better…making Truly Hands-Free really mean Trulyhandsfree™.

I haven’t had much time to blog lately, and you may have noticed that when I do, I often write about our revolutionary new Truly Handsfree™ Trigger speech technology. Technically it’s a phrase-spotting technology, but Sensory is using a revolutionary new multi-patent pending approach that’s changing the way we do speech recognition. The Truly Handsfree™ Trigger doesn’t use typical techniques like background noise modeling or speech detection (i.e. start and ending speech.) In operation, it ends up being MUCH more noise robust, yet still very efficient as it consumes less current than it would if we also included all the traditional approaches. The basic idea is that it’s on and listening all the time, and able to reject all of the wrong words and correctly identify the right words! This eliminates the need for activation via button pressing.
A lot of companies are using our technology now as a voice trigger for other speech recognition applications. At the recent Mobile World Congress, Samsung introduced the first Truly Handsfree Smartphone, the Galaxy sII, which uses a Truly Handsfree™ Trigger followed by the Vlingo experience. You say “Hey Galaxy” and it wakes up, no touching necessary! I tried this on the noisy showroom floor at Mobile World Congress, and it nailed my “Hey Galaxy” every time, even from a distance of 5 feet away!
Chris Schreiner over at Strategy Analytics recently tried out an early beta demo for Android, and in a blog late last year he said, “In a demo experience on my Android phone, the hands-free trigger worked remarkably well with varying types of background noise.”
With Truly Handsfree™ Trigger’s noise-robust nature and the ability to always be on listening, we are able to do more natural language-like schemes. A couple of great examples are in the toy space (and we do love toys at Sensory!)
So what’s happening here at Sensory is that this technology initially invented as a trigger is migrating into being an amazingly noise-robust speech solution for any command and control application! It’s nominated for awards by MobileTrax in both the Speech Processing and Software Technology innovation categories!
Sensory has developed a whole product roadmap around our new approach, and this includes speaker adaptive recognition, larger vocabulary solutions, improvements in accuracy, and consumer created triggers. A funny thing about consumer created triggers…Our initial release was NOT INTENDED for this, but one of our customers, Adelavoice, did a few tricks and allowed end users to create their own triggers. Know what’s the most common trigger phrase?? “Yo Bitch”…I guess that says something about the demographic of the user base!
OK…I could go on and on about this new phrase spotting technology, but I gotta get some real work done!
