'[EE] Voice Recognition of Numbers'

Hi:

Is there a simple way to add voice recognition for the numbers 0 through
9 and maybe a couple of key words to a 16F88 level PIC project?
I'm thinking there may be an IC that does this that's speaker independent?

Have Fun,

Brooke Clarke

Circuit Cellar ran an article on how to do this using a
microcontroller alone a few years back:

Also, a company called Sensory makes chips that do voice recognition:

Yes. Take a look at the VR Stamp (http://www.sensoryinc.com/).

That Circuit Cellar article is pretty nice! It seems that we could do
something entirely on a PIC now. Quite a bit more ram, eeprom, and flash
is now available (compared to 1998). You could also possibly use
comparators inside the PIC, though external filters and preamps would be
required. I wonder if something could be done with an analog input,
capturing the high and low frequency "counts" in real time off the ADC
(instead of capturing the waveform to RAM and analyzing later).

Warning:
Sensory make a product.
Next year it change the product. The former product is no longer supported.
Case Voice Extreme Kit and module.

Dennis.
