Praat is software which will perform many tasks relevant for phonetics. It was developed by Paul Boersma and David Weenik at the University of Amsterdam and is available for free from http://www.praat.org
Praat will run on Unix, Windows, and Macintosh platforms
See the Laboratory Manual for instructions on how to use Praat

http://www.phon.ucl.ac.uk/resource/sfs/rtgram/ESYNTH, Windows Tool for Harmonic Analysis & Synthesis Alternative to my "Vowel synthesis using sine waves" - more harmonics - also does Fourier analysis
http://www.phon.ucl.ac.uk/resource/sfs/esynth.htmESYSTEM, Windows Tool for Learning Signals and Systems Theory Alternative to my "Source & filter demo" - use a sawtooth source and a vocal tract filter
