Babble uses the services of speech-to-text and text-to-speech that are available via standard Android APIs. The apps that provide these services (e.g. Google Voice Search for speech-to-text, various TTS engines for text-to-speech) have to be installed separately in case they are not already pre-installed.
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. For more information see: http://vhackandroid.wikia.com/wiki/Babble
Known bug: after changing the selection of active languages you must relaunch the app for the changes to take effect.
Work around Google Search bug/feature, see more at:
