Praat

Praat is a speech-analysis application with tools for inspecting pitch, formants, timing and other acoustic properties. It is useful for voice research, detailed dialogue examination and educational experiments with sound. Its interface reflects phonetic analysis rather than studio mixing. Measurements depend on appropriate analysis settings, so inspect the documentation before interpreting automatic pitch or formant tracks as definitive results.

A useful display begins with a clear question and appropriate measurement settings. Confirm important observations through listening or a second check, and document calibration where absolute measurements matter.
