You can find the app on Android market as well:
|Plaphoons for Android|
It contains a pre-installed set of symbols for French language. Therefore, the text-to-speech configuration has to be switch to french! Ideally a better TTS-engine and voice should be installed.
The sets of symbols are defined in the same format as the Plaphoons tool. The Plaphoons tool can be used on a PC to design the set of symbols. The user just have to upload these files onto the tablet. It is planned to enable the upload and management of the set of symbols through a web platform.
