[net.periphs] wanted: text-to-speech synthesizer recommendations

We are planning to purchase a text-to-speech synthesizer for some
engineering shows we are giving to local junior high schools.
Could anyone suggest a good model?  It must be good enough quality
to be understood at the back of a classroom.  Ideally, it should
take ASCII input over an RS-232 cable.  Alternatively, a plug-in
board for an AT&T PC6300 (IBM PC compatible) could be used.  Also,
could you recommend a supplier?  We will need it by the end of
March.  

Thanks in advance.

	I have seen and heard a number of text-to-speech boxes including
VOTRAX's and the original speak(6) program which came with early versions
of UNIX.
	The only text-to-speech box which I consider "fair-to-good" in
terms of speech clarity and quality is DECTalk. Unfortunately it is $4000.
	The others, like VOTRAX's Type-and-talk are sort-of-okay. It is only
$250, but the quality is at very best "fair" and often "poor". I wrote
a simple preprocessor to the VOTRAX box which recognizes words and "rewrites"
the word to produce better speech output. Often the box gets fooled and
the output is rather unintelligible. With the preprocessor, one can even
give the box a bit of a French accent. But it begins to involve massive
table lookup.
	In short DECTalk is impressive, though far from perfect. The others
I've heard are pretty bad and should at least have some preprocessing help.
