speech recognition system

Hi everyone,

I'm doing a project using cyclone II DE2 altera board.

Anyone have done or read about this title?

Can teach me how to do the coding part?

Thanks you very much

    It is not trivial to get speech recognition works reliably. I did not work on it myself.

    This is what I read and think. There are a few key pieces,

    - Voice capturing

    - Zoom into section of meaning section

    - DSP functions like Fourier transform to extract parameters like pitches and durations

    - Compare against parameters of words stored

    - Training mechanism

    So, you'll need to be specific on which part of coding you are after.

    Thanks Tzestan

    I have research some journal about it

    but i can't complete the coding

    do you have any reference source code?

    I believe journal articles focus on algorithm. Even practicality may be left out. You still need to work out the coding yourself.

    But sorry, I don't have usable codes.

    If this is a school project, and you are not knowledgeable about FPGA or speech recognition, you may want to consider changing the definition of your project before too much time passes. As tzestan mentioned, there's a lot to it.
