I'm building a project and I need to use voice synthesis. Something like
National Semiconductor's Digitalker would be great, but the vocabulary is
limited.
I have two questions:
o Are there any really good (not too expensive) phoneme
speech synthesizer chip? The SP0256-AL2 isn't too good.
I've heard that the SSI-263 is better. Are there others
that are intelligible?
o Also, does anybody have any experience with using CODECs
or other chips to digitize speech? I'd like to be able
to find some sort of compression technique so that I
wouldn't need a lot of EPROMs. But, I'd like to hear
from anybody who has experimented with digitizing speech.

There is an interesting article in November's issue of 73 magizine (amateur radio periodical) that discusses a voice chip made by TI and a setup to allow creation of new words. It would give you a good start on your project. -- _____________________________________________________________________________ Steve Schallehn | Internet : sjs @ phobos.cis.ksu.edu Kansas State University | UUCP : ..!rutgers!ksuvax!phobos!sjs Manhattan, Kansas | Bitnet : STEVE @ KSUVM

Back issues of this can be obtained by calling (800) 432-6600 (this is the AT&T customer information center). It has a lot of speech processing techniques as they apply to telephony, but it also explains a lot about the mathematical methods used to process sound digitally. From what I understand, there is a lot of theory behind speech processing beyond the basic A/D converter and sampling. It would be interesting to see a discussion about this on the net, but I'm afraid that I wouldn't have a whole lot to offer thus far. -------- Gil Kloepfer, Jr. U-Net: {decuac,boulder,talcott,sbcs}!icus!limbic!gil ICUS Software Systems Voice: (516) 968-6860 [H] (516) 746-2350 x219 [W] P.O.
