security system password by voice recognition commands

HI everyone, i'm starting in the world of DSP, i have a project its a
security system by voice patter recognition, and i have used
pic16f877a in others projects, but it seems not enough for dsp, thou
it has a ADC converter 10 bit - fmax = 20mhz, and i was thinking to
combine with fpga spartan 3a (sending the digital signal to spartan
and then maybe do some fft and filter processing ) ... but i friend of
mine has a  TMS320 C6713 dsk and he told to me that is better with it,
i new in all of this, i dont know how to use C6713 dsk ...so i need
some advice, baby steps that i could take to do this project, please
someone...

Have you tried asking on an appropriate forum, such as 'comp.dsp'?

It would be quicker to develop this algorithm for a DSP dsk rather
than an FPGA in my opinion.  It would possibly be cheaper to
manufacture in an FPGA especially if you need an FPGA anyway in the
overall design (Xilinx S3A-DSP, for instance).  The algorithm
development would probably be the bulk of your design "IP" yet going
to an FPGA would make transcribing that algorithm to the hardware -
even dedicated DSP48 blocks (or similar) - the largest part of your
development.

FPGAs are fantastic vehicles for getting fast custom logic into a
small footprint, both mechanical and cost.  But for a single project?
Not so helpful when the algorithm gets complex.  At least that's my
experience.
