Q: speech toolbox?

I recently dicovered octave and would like to use it for short 
experiments. As I am working on speech research, I was wondering 
if someone has already developed a toolbox to deal with speech 
signals, e.g.

- read/write audio
- compute FFT, spectrum, LPC, cepstrum, F0, formants, autocorrelation, ...
- windowing (hamming, hanning, ...)
- filtering 
- filter design
- clustering (k-means, ...)
- computing gaussian mixture models
- training, evaluating HMMs 
- ...

If so I'd be very grateful for any hints where to find that 
toolbox and how to use it :-)
