Praat Speech Analyser
According to its authors, Praat Speech Analyser is "doing
phonetics by
computer". Through
its graphical interface, several speech analysis functionalities are
available: spectrograms, cochleograms, and pitch and formant
extraction. Articulatory synthesis, as well as synthesis from pitch,
formant, and intensity are also available.
Praat is configurable and extensible through its own scripting
language and has provisions for communicating with other programs..
