Hi, I was wondering if anyone could tell me what type of DSP i would need for a basic voice recognition system. The system would you a matched filter of 1000 samples and can have a sampling frequency of anywhere from 2200 toi 22050 Hz. Also the samples have a resolution of 16 bits. I'm confused on what sort of spec it would require e.g. in MIPS or MFLOPS. Any help would be very much apprieciated. Thanks
