We are interested in incorporating a voice recognition device in a system that needs to recognize just two words: YES and NO. Ofcourse, the recognition mechanism must be speaker-independent and would be helpful if it can be implemented using a microprocessor with limited memory and processing capabilities. If you are familiar with any off-the-shelf product that is either commercially available or available for licensing, please send email to : rajha@cs5.usc.edu and a copy to rajha@girtab.usc.edu Thank you very much.

Voice Control Products, Inc, 1140 Broadway, Ny, NY 10001, (212) 683 4684 makes exactly what you are looking for. The device is in the form of a 20 pin DIP. One feeds clipped audio in, attaches some capacitors and a crystal to other pins and gets a logical output for "YES" and another for "NO", and another for "?" when it thinks it sees speech but does not recognize it. The chip consumes 40 ma at 5 volts. They have an evaluation board available that they will loan you for a $500 deposit (payable net 30). The cost of the chip ranges from $70 for one each to $1.90 in 100k quantities. I evaluated this part in 1987 for a client and found it to work as advertised. I'm sure that the technology has improved in the interim. And hopefully, the small quantity price has come down.

Radio Shack had a voice recognition chip that recognized yes, no, and some directions. I believe it sold for $12.??. -- %% Dru Nelson %% Miami, FL %% Internet: dnelson@mthvax.cs.miami.edu %%

>Radio Shack sells just such a chip (!) for around $10. I don't know their >part number... OK, I found it: The Radio Shack PN is 276-1308. "VCP200 Speaker-Independent Word Recognizer," they call it. The chip has two modes: In "Command Mode" it recognizes: "go", "stop", "reverse", "turn right", "left turn". In "Yes-No/On-Off" mode, it recognizes those four words. External components required: a handful of caps and resistors, and a 10 MHz crystal. The outputs are simply latched logic levels for each recognized word. You could do a lot with this chip and _no_ processor, so a small one should do fine. ----------------------------------------------------- Gordon S.

Beware of one thing: almost any voice recognizer is going to be somewhat unreliable, and that goes double for a one-chip speaker-independent system. They make nice toys, but using them for something serious could be a mistake.
