Please forgive me if this has come up before on this news group (I don't read it very much) but is it possible to get a PC to "talk" (synthesize some kind of recognizable speech, however artificial sounding) through its built-in speaker? As I understand the way the speaker is set up, the speaker is fed a binary signal, either controlled directly by the user or divided down by a user-selectable factor from an internal oscillator. It seems to me from a casual look at this design that the speaker could be pulsed at ultrasonic rates, making a crude kind of pulse width modulation waveform "synthesis" possible. But has anyone heard of this being exploited successfully to actually make the built-in speaker "talk"? (I'm not interested in special voice synthesizer hardware, just in tricks with the built in speaker.) If you have something you can tell me on this matter, please send me email if you can. I can't always keep a close eye on this news group. Thank you much in advance. -- Daniel R.

Yes, it is possible to use the PC speaker to do crude speech synthesis. I believe that there was a program on one of the bulletin boards here in Champaign that allowed a user to input phonetic strings and it would use them to make the PC "talk". I don't remember what the name of the program was but maybe someone in netland might. Heeren Pathak s.cs.uiuc.edu zaphod.ncsa.uiuc.edu
