Creates an interesting phonetician analysis of voices and speech

Praat is a piece of software that helps phoneticians analyze, synthesize, and manipulate speech.

Praat enables you to create a source signal from scratch or from an existing speech signal, but also to create a filter or to extract it from an existing source. You can manipulate (change, adapt) both the source and the filter before doing the actual synthesis, which combines the two.
