How to do speech processing using matlab?
For example- Take tomcat apps in iphone and android. If you speak something, it will speak the same in return but in a different pitch. I would like to process the speech signal. Which toolbox should I use?

I think there is a MATLAB wrapper for Praat, but I cannot find it quickly. You might want to try:

I did that by taking fft and considering only the first half of the spectrum.

If you can use the signal processing toolbox if you have it at your disposal. It has several filter commands you can use once you have loaded the sound file on to your work space.
