Speech recognition?

Are you able to use Speech recognition in the basic stamp 2? how
would i be able to do that? What i would like to happen is what i
said would match up in a database of the eeprom and would do an
action that i program it to. help? im sure this is possible

It depends on how robust the speech recognition needs to be. You
could easily make "The Clapper" with a Basic Stamp, which could be
considered a very rudimentary speech recognition sytem. You probably
could not make a system that could distinguish between the words
"fake" and "frank" using the Basic Stamp as the processing core.
Speech recognition is often done by sampling the sound of the voice,
processing the sampled data for frequency content, and then comparing
the result to known samples. You would need a peripheral A/D to
sample the data- those are available. You would need an FFT routine
to do the frequency analysis- I found no references to one in the
archives of this ng. You would need significant memory for a lookup
table and a "best match" algorithm for comparing to the known samples-
the Stamps limited memory and variable space would become significant
hurdles.
I wouldn't say it can't be done, but I would say there are much better
processors for the task.

couldn't handle the necessary high sample rates, using its Pbasic
Interpreter, for the necessary voice quality. This would require a fast
PIC, using either assembly or compiled code.

Motorola (or Nokia) phone with no service contract.....tell it to "call
home"....have the stamp monitor the output of the phone as it dials. Then
execute code based on the numbers it dialed.... Of course it won't cost
anything for the phone to attempt a call without a contract [noparse]:)[/noparse]
Sure beats reinventing the speech recognition wheel!!

Tim - HA! I like it! Excellent suggestion for a work around!
Dennis - if the A/D wouldn't be able to sample fast enough, we will
have to speak vvvveeeerrryyy sssllloooowwllyyy to our Stamps! ;-)
