The question:

I am looking for products that support the voice typewriter 
concept with a trainable recognition device that attaches to a 
computer word processor (PC Mac Sun) with a vocabulary of a few 
thousand words.  Can someone point me in the right direction.  
Thank you.


The replies:  (Thank you very much.)

John,

The recognized leader in discrete utterance, large vocabulary,
"speaker independent" voice recognition for PC's is a company
called Dragon Systems. "DragonDictate" is probably the engine
you'd want.(20-25k base vocabulary suitable for dictation, plus
a 5k "custom vocabulary")

WordDancer Systems, a company based in Edmonton AB, Canada, produces
and markets products based around Dragon's engine. Mostly WD's clients
are "keyboard disabled" professionals (M.D's, lawyers, engineers for ex.) 73 
macros using every-day word processing products such as WordPerfect.

Discrete utterance is not as restrictive as it sounds, true, you have
to insert very brief (10's of ms) pauses between words or recognized
phrases(word macros), but some of WD's legal clients get up to 80 wpm.

DragonDictate's current price is around $5k US. A Digital Signal
Processing board is added to your PC to do the front end acoustical
feature extraction. Plus you need a fair bit of memory, 8MB minimum, 
16MB+ recommended, and at least a 386 processor.(memory management)

I don't have Dragon's number off hand, I do have WordDancer's though,
or, if you have specific questions, I can email a response.(I know the
principals of WordDancer)
