Voice recognition on embedded hardware.

Just wondering if anyone knows how plausible it would be to implement voice recognition system in hardware (eg a PIC).

My experience so far is purely software, and the applications are quite large. Has anyone heard of such ventures in the past?

    It's a very possible idea. I've done some speech (not voice )recognition on Windows platform with not to many lines of code. I also intend to implement it in assembly (for an embedded OS). It depends on what u want to lose (accuracy, vocabulary size, etc) and most importantly on how efficiently you can translate your formulas into your target's machine code.

    Thanks for your reply. When I made the post I was not aware of the distinction between the two recognition types. I am interested in speech recognition with a vocabulary of less than 100 utterances.

    Could you reccomend any reading material or online resources?

    Which speech recognition algorithm do you want to use? As I know common reliable methods need a lot of system resources and in this case PIC isn't good choice.

    I have not yet chosen an algorithm. My knowledge of DSP is pretty basic. But I think the level of reliablility I want clashes with the low cost that I also want.

    I was reading about these on last few days, and I find a project based on HC05, with no ADC: it's a project called TinyVoice and I still can't understand how it works.

    Does any of you have idea of the algo it's using?

    Thanks in advance!
