Babble shows you short phrasessentences in many different languages and you39;ll have to pronounce them quickly in 4 seconds and correctly. The app will give you feedback on your pronunciation skills. You39;ll be able to see your improvements over time.Babble uses the services of speechtotext and texttospeech that are available via standard Android APIs. The apps that provide these services e.g. Google Voice Search for speechtotext, various TTS engines for texttospeech have to be installed separately in case they are not already preinstalled.The current version is a prototype. The core of it was developed by 3 Android enthusiasts over a weekend in the beautiful library of Genk, Belgium, as part of the V Hack Android hackathon.
