Real time acquisition of speech samples

Hi All,

I am working with cyclone DSP development board. But I don't know how to use the MIC IN and audio in ports. Let anyone explains me how to acquire speech samples in this kit. Or please suggest some reference examples/documentations.

Thanking you,

Amudha

    the mic will most likely have to go to some sort of ADC or Codec... i'm not familiar with the dev. board, I don't know. But there will be something to digitze the data. Then it's a matter of simply collecting samples at whatever rate you want. Give more info and I can perhaps help you out some more.

    Thanks for your reply.

    The DSP development board has mic port as well as ADC. my doubt is how to acquire the samples from C code.

    regards,

    I'm also working on a project for voice recognition and one of issue I have is how to get the input voice from a mic to a VDHL coding. Is there a templet/example of a code that can guide me through the beginning stages of my project? Thanks for any suggestions.
