speech recognition system

[Altera_Forum]

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 castle zone

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.

This doesn't have anything to do with Altera FPGA, but the venerable CMU Sphinx recognizer http://cmusphinx.sourceforge.net/ is probably as good a starting point as any.

wow ted 

your link very interesting but my project is related with altera FPGA board

As tzestan mentioned, there's a lot to it.
