You are in luck.  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.
