are you sure understand my requirements... Text to Speech ---> at phone conversation ? not to speaker (How just using tts)
play messages at phone conversation not to speaker
pre-defined menus IVR like - Press 1 to go to menu B - Press to 2 to go to menu C - Press 3 to listen again the messages (at phone conversation not to speaker) (an example ?)
???
Not; now i'm (almost) sure
You want to "listen the voice" during phone calls and use that for various operations.
I had read too fast ... and the text is not exactly in Italian
So, I don't know the answer (although I believe that it is unrealizable)
Sorry
P.S. I was thinking.
The S.O. should allow some of those things; in fact, allows you to record a telephone conversation. Perhaps using some trick, then it would be possible to use the recording by sending it to the TTS (sorry, I do not know how to explain better what I mean. Anyway, I do not know how to do, so I can not help you)
