TouchSpeak on the PDA/Phone

A non-vocal person using a TouchSpeak enabled cell phone can make phone call and talk on the phone using his computer generated voice.

The communication system can be picture based using any of the standard symbol systems or text based with word prediction. One could even write on the screen with a stylus and the written text with be converted to speech and spoken to your listener whether that person is standing next to you or on the other end of a phone line.
