iPhone owners can now perform a Google query with the sound of their voice. Google Mobile App has long been one of the most useful iPhone apps for finding local search results, querying Wikipedia, or even quickly sifting through one's own address book, and thanks to a major update, users can speak virtually any search phrase into their iPhones and receive quick results for things like photos, the nearest coffee shop, and local movie showtimes.
Let's take a look at how it works. Available for free from the iTunes App Store, Google Mobile App (iTunes link) presents the company's trademark simple search interface, into which users can type general queries, or specific searches for a wide range of data types, incluing the web, contacts in the iPhone's address book, maps, images, news, shopping, and Wikipedia results.
As we previewed last Friday, this new version of the app (a verbose 0.3.142) brings voice searching, where users simply hold the iPhone up to their face and speak their query. Note that while most of Google Mobile App and its text-based features will run on an iPod touch, the vocal search feature is only compatible with the iPhone for now, and only in English. A number of other features and changes arrived in this new version, but we'll look at this vocal search feature first.
Google Mobile App takes advantage of the iPhone's proximity sensor to start and stop voice recording, and the audio file containing the voice query is sent to Google's servers for processing. The iPhone's location-based features are also automatically harnessed when necessary, and results are provided pretty quickly over WiFi and 3G.
