Hi. That's a very interesting aproach. I guess also that putting the synth through a mixer and doing some equalization could produce similar results. When listening to ACBRadio's main menu, the doubletalk sounded pretty good, actually, probably because of a combination of mp3 filtering, caused by lower sample rates, and mixing.

I have used both and like the performance and speech of doubletalk over the other. To modify the sound quality, but not the nature of the speech itself, I have found that placing a folded thick cloth over the speaker on the doubltalk lt. shapes the sound output in a more natural way, filtering out some of the extrainious higher frequences above approximately4 kh. This is the range above which the telephone cuts off speech also for best intelligibility. The sound some find objectionable is in my experience a matter of extrainious sounds created by the speaker in the synth. box, very cheap junck, and not the text to speech chip itself. Using a combination of cloth filtering and the sound controls of the speech software, one can greatly modify the sound quality and intelligibility to one's preference. I would imagine this approach works also with the internal doubletalk and it's external speaker. xv ic|xc _______________________________________________ Speakup mailing list Speakup at braille.uwo.ca http://speech.braille.uwo.ca/mailman/listinfo/speakup --- Incoming mail is certified Virus Free.
