- 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.)
