Abstract:Human speech consists mainly of three components: a glottal signal, a vocal tract response, and a harmonic shift. The three respectively correlate with the intonation (pitch), the formants (timbre), and the speech resolution (depth).

Second, its speaker-tuning reduces background noises to clarify acoustic observations. Third, extracting the… Show more
