When you say "frequency curve", do you mean a frequency spectrum display? What you need is a package that allows you to do an FFT on a section of the speech sample, and then plot the frequency domain representation of the speech signal. I am working on some similar applications and I use LabWindows from National Instruments, Austin, TX (1-800-433-3488). In particular, they have a DSP library that controls their Digital Signal Processor boards (although I believe they have libraries that emulate the board - they just take more time.) --- Gary J.
