I am going to be involved in a project in which I have to analyze 
speech signals. These speech signals are delivered as MU-LAW PCM 
data, sampled at 8000 Hz. After transforming the data to linear PCM, 
I want to perform a fourier transform, using approx. 10 ms data a time.

Does anyone know of a good FFT algorithm for short-term sequences? I
already experimented with the algorithms mentioned in "Numerical Recipes in
C" but I had several problems with them. 

A second question; Are there any good books on digital signal processing
with regard to speech processing?

I will summarize to the net; this will take some time because I'm not here
during the next week.


Thanks in advance for any information,

Johan Thole.
