Just suggesting: maybe a little web server (python?) in the background that could be called like "http://localhost:9999/talk/turn_right". The server would then either use espeak or prerecorded files. I might give it a go, but rather stretched on time today...

Thanks again for all your work!

Joerg

UPDATE: ok, I stole some time away, and quick-hacked a little python talk server.

- install espeak
- call 'python speak.py' in the terminal. Or 'python speak.py german' for a german talking server
- the server could then be called on http://localhost:9999/turn_right. The call returns immediately (either with the command spoken, or with 'error'), and the talk can be interrupted with a new request. Only knows turn_right and turn_left, but maybe enough for testing?
