Google's Voice Search feature which allows users to do searches through voice is getting a nifty update today, particularly for users in France, Germany, and Japan.
Yes, French, German, and Japanese have been added to the list of supported languages, if there was any except for English, on Google Search. The S.O.P. remains the same: tap the microphone icon in the search box and ask your questions.
Don't worry about getting a reply in English, as the app can also return spoken answers in French, German, and Japanese. And, lastly, don't forget to download the latest update.
