The secret of Google's amazing voice recognition revealed: it works like a brain
Share:
And while we were impressed with Siri when it first launched on the iPhone 4S in 2011, it was Google’s Voice Search swift and almost flawless voice recognition technology that has set the bar this high for voice.
But how does it work and what makes Google’s Voice Search so good?
We've heard it before and now we get one more confirmation that the inspiration for it comes from the neural networks in our brain. The implementation of the ‘neural network’ started in Jelly Bean and brought a whopping 25% drop in voice recognition errors.
Basically, using such ample cloud processing power, Google can analyze a ton of patterns - which in case of voice are spectograms - and use that to predict new patterns, much like the neurons in the brain would reconnect to accomplish new tasks.
There are a couple of layers in processing speech. First Google tries to understand the consonants and the vowels. That is the foundational layer. Next, it uses those to make intelligent guesses about the words. And then higher.
The same approach is actually applied to image analysis where you try to first detect edges in an image. Then check for edges close to each other to find a corner. Then go higher from there.
It’s all a fascinating revealing piece on the bits and pieces the future will be built on, and if you’re interested you can hit the original article at Wired below for the details.

The difference being that Google isn't interwoven with the military, and isn't likely to be (other than Android phones being used).

And how exactly could you be so sure about that?
I actually BET that all data from your phone (not only Android, but iOS, W8, etc) are gathered somewhere to make a nice huge file for you (the user).

That is pretty fricken' sweet. And people say that Google isn't pushing the envelope of technology.

before long, google's voice search will start to develop a personality by itself...unlike siri which is actually programmed by humans to do so.

Five years back and i might have believed in you...but nada, this is the real thing. It ain't a gimmick anymore...
Where you been? How long have you been hibernating?

Siri - when it doesnt or didnt recognize something....it shows or recommends a picture of stallions.
Google Voice recognition- it rarely doesnt recognize you.
So...are you saying all voice recognition is a gimmick...or just Google's version....also...Google Now...was setup to just give you infomation based on searches and other things you can setup. Siri had an update to do similar after the fact.
I'm just curious what you think is a gimmick...

But Siri can give you a witty, preprogrammed canned response.

Honestly Google voice just destroys s**tVoice by Samsuck
I speak with a heavy Asian accent , and surpirsingly Google Voice manages to get things right 95% of the time !
I do like the personality of Siri though , but its slower and Google voice does a much way better job at interpreting your words .
SVoice though , its just terrible

i agree that S-Voice sucks
but I don't agree With you saying "Samsuck"
that's disrespect to one of the best smartphone makers
I never use S-voice on My Note II
Google voice search is better, smoother, and most importantly FASTER
Samsung will make everyone's jaw drop announcing the S4 and Note III

"It all started materializing to users with the iPhone 4S and Android devices of about that time"
Nah, PA as usual skewing the facts towards Apple. Not even close, Google had solid voice commands in 2009 and the fantastic Google Now, well now... Apple had no such service until late '11
