Speech Recognition IC (voice control of circuits)

[[email protected]]

I am interested in an IC that can accept spoken commands to control
circuits.

Can anyone help?

please post part numbers (and/or links)

Thanks

TI has DSPs that do this. Don't know if you want to go that route.

A company that uses TI chips to do this for embedded world and sells to Toy
makers:

Phillips has a low cost chip solution for that:
http://www.futurlec.com/News/Philips/SpeechChip.html

" The Hello IC is able to interpret the equivalent of up to 100 words with
up to 50 words active at a time and features continuous connected word
recognition, enabling the user to give whole sentences of instructions. The
Speech Processing software - VoCon - which is stored on the chip and
requires no external memory, also features noise cancellation software
enabling the Hello IC to work in situations where background noise could
otherwise affect voice recognition, such as in a car with an open window. "

And a TechOnline article on an Academic system that does that at:

Google for "speech recognition" and IC

Or "voice recognition" and IC and you should get plenty of hits.

The Radio Shack chip was called the VCP200 by Motorola. They are no
longer available.

The TI chips can handle text to speech and speech recognition but you
would have to buy third party software for your application.

The Sensory Chips are a good option but require expensive development
kits and lots of custom coding.

The Phillips chips never really made it into production as far as I can
tell. It is not available.

Haven't read the paper but it looks like a custom designed solution.

My conclusion is that sensory is the best option but only if you plan
on doing production runs not if you're a hobbiest. Other than that,
there is no hobby level speech recognition IC on the market.
