Need help on voice recognition circuit

[vead]

Hi,
I need circuit that get voice from particular person and work on certain operations actually i want to design robot that operated according my voice instruction
I know about HM2007 but i can't arrange this Ic
please anybody help me how to design voice recognition circuit what component i need to make circuit
thanks

ICs and micros only have so much computing power and are limited to the mere basics...

If you want the best of the best you will have to consider a full fledged single board computer running voice recognition software... The good thing is that single board computers are cheap now and you can run Windows or *nix on them off a flash drive or solid state drive, all in the space of about the average paperback book...

Here is a paper on the subject. It may give you some ideas.

Is it possible to make analog voice recognition circuit

You mean something that doesn't use software?

Practically... No -- unless you can find a device which will do it for you.. But even then, I'd bet it would require a microcontroller (at least) to drive it.

hi steve
you mean i can make analog voice recognition circuit if i use microcontroller with circuit

Possibly a very very crude one that could detect bigger fluctuations... This article describes how it's done...

As I said you are much better with a single board computer that has the CPU crunching ability and storage space, but if you insist on a micro look at Microchips dsPIC chips they have some official documentation on voice recognition...

hi everyone
finally i think i should use voice recognition IC but in my place HM2007 Ic is not available there is another options to replace this Ic
