Users can soon ask their iPhone a question and get search results from Google (GOOG) thanks to a soon-to-be-launched application on the Apple (AAPL) iPhone apps store.

According to news reports and blogs, the voice search application, which was expected to be unveiled on Friday will be available for free at the apps store later Monday. At press time a search of the apps store showed the applications wasn’t available yet.  

The software lets you ask questions from where the closest Best Buy (BBY) is to which baseball team won the most World Series. The application translates the spoken word and spits back local results. It’s the first application of its kind for the popular iPhone.

According to Wired, the application was suppose to go live on Friday but Apple didn’t add it to its store, underscoring how Google is subject to the same review process that other software programs for the iPhone is.

While voice recognition has been used at call centers for years it’s now starting to take off for mobile phones. 

vlingo, a Cambridge, Mass., speech-recognition technology company, earlier in the year launched a service for the BlackBerry (RIMM) that lets you make phone calls and search the mobile Internet via voice commands. 

The software, which can be downloaded at vLingo.com for free, will translate your speech into text and send back text-based information. For instance, if you want to know the address of a restaurant in Boston or what the weather will be, all you would have to do is ask your BlackBerry. The service lets users send emails and text messages, search the Web, open applications, dial phones and look up contacts.

Tellme, a subsidiary of Redmond, Wash.-based Microsoft (MSFT), also has a voice activated service for BlackBerry. Like vlingo, Tellme’s service is free to download and lets you access information like directions, movies, traffic information and weather via voice. Since Tellme’s service works with the local Internet it can recognize your most recent position based on GPS and give you local results. If you say “maps” you’ll see a map of your current location. You can change the map location by saying a different city. You can also get movie listings, buy movie tickets, see weather reports and traffic updates simply by saying the keyword from the main screen.
