DoubleTalk stil going strong

[Arthur Pirika]

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.

Arthur.

Regarding dectalk and doubletalk speech, some of us prefer the latter.
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.
