iPhone search by voice

Not sure if I’d try this on a plane or a train, but Google is planning on offering an application for the iPhone which will allow people to search using the sound of their voice rather than the pad of their finger.

Google is expected to release a free iPhone application today that lets iPhone owners ask to find local businesses, get driving directions, ask basic search queries (“What’s the capitol of Belgium?”), and displays them on-screen “within seconds on a fast wireless network,” according to the New York Times.

The sound of our voice is converted to a digital file and sent to Google’s servers, which try to determine the words spoken and pass them along to the Google search engine.

The search results, which may be displayed in just seconds on a fast wireless network, will at times include local information, taking advantage of iPhone features that let it determine its location.
