German speaking volunteer wanted


Hello all,
I have made a new version that can speak two languages. Main language remains English, the other one is optional. It switches automatically in dependency on the callsign input.  I look for a native german speaker to tweet the German language. It concerns setting the right voice (Stefan, Hedda?), inputting german spelling words (Anton, Berta, Caesar, ...?) and overall testing of usability. In return for this the full licence will be granted, of course. Any such person available?
