Google Adding Voice Search to iPhone

The Google Mobile team is expected to enhance its iPhone search product with a voice recognition add-on as soon as today, according to a report in the New York Times.

Having already reorganized the way it delivers the results of an iPhone search request earlier this week, the Mountain View, CA search engine company is taking another step toward perfecting the way it handles the challenges of entering and retrieving information with hand-held wireless devices.

“Solving those two problems in a world-class way is our goal,” says Vic Gundotra, a former Microsoft executive who now heads Google’s mobile businesses.

With teams of voice recognition engineers working in New York, London and Mountain View utilizing trillions of search queries Google users have made over the years, one aspect of the service relies on a statistical model of the way words are frequently strung together, according to Mike Cohen, a speech research who was co-founder of Nuance Communications before coming to Google.

The service also takes advantage of the iPhone’s accelerometer to put itself into “listen” mode when the phone is raised to a user’s ear, a design development contributed by a Google researcher in London.

Both Yahoo and Microsoft already offer voice services for cellphones. The Microsoft Tellme service returns information in specific categories like directions, maps and movies. Yahoo’s oneSearch with Voice is more flexible but does not appear to be as accurate as Google’s offering, according to the Times report.

The Google system is far from perfect, and it can return queries that appear as gibberish. Google executives declined to estimate how often the service gets it right, but they said they believed it was accurate enough to be useful to people who wanted to avoid tapping out their queries on the iPhone’s touch-screen keyboard.

As of this writing the add on was not yet available on the AppStore, but as Raj Reddy, an artificial intelligence researcher at Carnegie Mellon University says, “whatever they introduce now, it will greatly increase in accuracy in three or six months.”
