Google Voice Search now works in 13 more languages thanks to an update by Google [GOOG]. In total that makes the software support 42 languages which are found in 46 countries.
Over the last few years, Google has wanted to make search far quicker. On the desktop and mobile they introduced instant search where you type a search and the results are updated real-time, without hitting enter. Also to speed up search they added voice search so that you can say something rather than type it as this is also generally quicker for most people.
