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.
