International Voice Search users rejoice! Google's ever-evolving search service has been updated to add another 13 languages, bringing the total to an incredible 42 languages supported. The list of new languages should make a lot of European Android users happy. It includes Basque, Bulgarian, Catalan, European Portuguese, Finnish, Glacian, Hungarian, Icelandic, Norwegian, Romanian, Serbian, Slovak and Swedish.
With this update, Google claims another 100 million people will be able to use the service in their native tongue. Voice Search can only get more accurate over time with additional users, as Google uses the search queries to improve the service. This is simply a cloud-side update, which means that no additional action should be required to start using the new languages -- outside of possibly changing the device's default language.
