Google announced last week that the voice answers to voice queries can now be answered in three international languages.
So now instead of Google Voice search only responding to some queries in English, it also works in French, German and Japanese. Google promises to bring more voice responses to other languages in the future.
You can try this out yourself if you are on the latest Google Search App on your iOS or Android device.
Mobile search is growing not just in the US, so be prepared.
