The secret of Google's amazing voice recognition revealed: it works like a brain
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.
