Microsoft uses human brain to boost speed and accuracy of Bing voice search

Microsoft is taking tips from the human brain in its latest Bing for Windows Phone app update.

The Redmond-based firm has promised improved speed and accuracy with voice to text and voice-based search for Windows Phone users.

"Over the past year, we've been working closely with Microsoft Research (MSR) to address limitations of the previous voice experience," the Bing Speech Team wrote in a blog post. "To achieve the speed and accuracy improvements, we focused on an advanced approach called Deep Neural Networks (DNN)."

The technology was inspired by the functioning of neurons in the brain; similar to the way the human mind listens to and interprets speech, the DNN system can detect and recognise patterns.

Give it a go — Ask Bing where you can find the best pizza in the city, and the app should return results twice as fast as before, with 15 per cent increased accuracy.

"As the scientists continue to explore the expanding frontiers of the DNN work and to collaborate accordingly, the DNN-fueled speech-recognition improvements can only continue," Microsoft Research's Rob Knies said in a separate blog post. "Broad-scale speech-to-speech translation, once simply a dream, suddenly seems an alluring possibility."

Need to text a friend from inside a crowded, noisy restaurant? The new Bing to the rescue. Redmond tooled around under the app's hood and made it easier for its voice-recognition service to identify speech patterns and cut through ambient and background sounds, also cutting response time in half, and improving the word error rate.

"This is only the beginning of Bing's work to improve speech and voice capabilities across Microsoft devices and services, and you can expect more from us in the future," the company wrote.
