[comp.sys.ibm.pc] Speech Synthesis / Voice Recognition

I have recently become interested in the use of Speech Synthesis and Voice
Recognition on the PC.  What I want to know is are there any _good_
sounding synthesizers, and how good does the recognition work.  For the
sake of argument, let's say money is no object, but also I want to know
about the lower priced boards, like Hearsay 1000.  How much help can
a VR system be in terms of time saved from typing?  

Any help would be greatly appreciated.  

E-mail to me and I will post a summary if necessary.

Thanks.

On the synthesis side:  Heathkit (Griefkit :-)  ) sells a PC phoneme synth
board for under $100.  It is based on the SP0256 chip that was featured in
one of Ciarcia's Byte articles a few years ago.  I have not heard the chip
but it probably sounds similar to the Votrax SC-01.
If anybody out there has bought one of these and has made it talk with
Turbo C, I would be very interested in hearing about it.
I don't know if Heath provides any interface routines, but driving the
board should be fairly simple.

Plusses of Phoneme Synthesis:
- Low data rate < 50 B/Sec.
- Easy to write English to Phoneme translator programs.
  (one was posted to the net a few years ago, it is ~probably~ on SIMTEL20)

Minuses:
- VERY mechanical sounding output,  It takes a while to learn its dialect so
  it is not very good for dealing with the general public.
- Usually only one voice type on the chip.
