The voice command on smart devices become increasingly popular, one of the existing Google Voice Search on Android Jelly Bean. Amazingly, it turns out this system works like the human brain.
Voice commands began fame after the appearance of Apple's Siri in the iPhone 4S by the end of 2011. This feature can be used to find the nearest restaurant, view weather forecasts, check the schedule, and a few other mild things just to rule it.
At that time, Google Voice is still limited to voice commands and can not compete with Siri, but gradually becomes wider functions and more sophisticated so that it can be an alternative to Siri.
But behind the Google Voice functionality is easy to use it turned out the way it works quite complicated. It could even be comparable to system of the human brain which is inhabited by millions of nerves.
"When you talk to Google Voice, the spectrogram is spoken will be broken down and sent to eight servers owned by Google. Data is then processed using a neural network model," said Vincent Vanhoucke, Google scientist who made the application.
Furthermore, Vanhoucke explains how to work the Google Voice that the whole process is done in the 'cloud'. Google also claims to have a lot of sound patterns that can be used to identify the order mentioned, and these patterns continue to be developed in order to more precisely identify the user's commands.
"Google Voice in Jelly Bean has further reduce error as much as 25%," added Vanhoucke.
There are several stages before Google Voice to recognize what the user ordered. First, the system will try to recognize the consonants and vowels of the user, the data is then used to 'guess' the command is meant.
But not merely a guess, here Google claim to have answered patterns using neural patterns that exist in the human brain. So the results are expected to be more precise and the engine can respond naturally.
Not just a voice command, it seems Google will use patterns of the human brain to develop their other products.
Even so, it still must be recognized that the work of human beings will never be compared with God's creation that much more perfect.
