It's a good news for Google Lovers that Google Voice is Available in 38 languages. So that you can search as per your desired Language.
Google Voice is an interesting tool I used it in English language. You have to just speak and it searchs according to speaking words.
Thats sounds interesting especially on your mobile device when you are on the go most of the times. I wonder if any one has searched it in their own language and how is the results? Just wondering if it works in Nigerian language
