    Hi Guys,
    I just wanted to inquire on the feasability of implementing a voice recognition system ( to be able to detect basic speech commands, speaker independant) on an FPGA or DSP ( basically without the use of a computer) . The idea is to be able to use such speech to control motors for various applications.

    If anyone has experience with such a field, I would appreciate your comments.


    P.s: I also wanted to know whether or not it would require the user to "train" the DSP or FPGA.

    Might be better off with a PIC than an FPGA. We did it with a TRS-80 back in the '70s. I suspect any old modern PIC would run circles around the TRS-80.

    Training was required back then. We had to train for each and every different human, and had problems if someone came down with a cold.

    There are simple and easy to use speech recognition ICs available. These are quite good with excellent rate of detection but usually are limited to ~ 20 to 40 words (commands) or so. They are not that expensive, less than $20 each depending on model, and not difficult to link to a microcontroller system. Search for HM2007, Sensory, OKI or Philips.

    is hm2007 still in store?
