Using DSP/BIOS for Speech recognition

Started by abdul muqeet February 21, 2007
hi ,this is muqeet pursuing my mtech n working on a project that is Speech recogniton using DSK 6713.I ve used the audio example as a reference.which is using the DSP/BIOS.This audio example is using the audio signal only to transfer it from PC to DSK .For this example i m connecting the audio signaI to dsk on the LINE IN and hearing the same audio signal from the headphone out.But Wat i would like to do is to add the lpc algoithm(Feature Extraction algorithm ) in the place where the source to destinatin data transfer is given in the code.
Secondly i would like to use the memory function i.e MEM_alloc to store the speech data in the SDRAM.
Could any body suggest me how i can configure the dsk for this memory allocation and how i can incorporate the lpc algorithm in place of the audio example algorithm.
