Voice search has been one of the features in which Google has put more work for a while now. It has looked for the way in which the user can interact with it so that it is able to launch phrases and all kinds of context so that the results are more precise and appropriate to what one is looking for. A perfect functionality for what Google Now is and those recommendations that appear on the screen and then use the Ok Google command or press the appropriate icon to launch the voice search.
If these days you have noticed that Google's voice recognition is working better of what I was doing, it is because of the improvements implemented. Today Google has reported that the capacity for voice search is now being managed by a new engine that recognizes and anticipates words with a greater degree of precision.
New engine for better voice recognition
Google says those improvements are thanks to development of acoustic models of a neural network using different techniques such as the Connectionist Temporal Classification (CTC) and a series of sequential discriminative training techniques.
From the Google Research Blog itself, members of Google's speech recognition team, including Haşim Sak, Andrew Senior, Kanishka Rao, Françoise Beaufays and Johan Schalkwyk, maintain that 'These models are a special extension of the recurrent neural networks (RNNs) that are more precise, and that behave in a quite special way in environments with noise and that at the same time they are surprisingly fast'.
In short, Google now works better at correctly recognizing what you say to it, especially in situations where there is background noise important and in what it would be to reduce the delay time between speech and interpretation.
A 2015 with changes in voice recognition
We face the second time this year Google announces enhancements to voice search capabilities. The current neural networks that Google is using for its voice models are used more extensively in what artificial intelligence is called "deep learning."
With those Google's intentions for roboticsNor does it surprise us that he is putting everything into the development of the functionality of a better voice search so that the interaction between a human and a computer is in a better way.
This new update, as it comes from the server side, is already functional both on Android as in iOS, so you can go and test it with that "Ok Google" command and check if it really recognizes everything said.
Another one of those advances that Google is branded in this year and that greatly improves the quality of a service such as voice search and Google Now that provides it shelter.
