How Are Harmonics Produced at the Voice Source?

by Ingo R. Titze

In summary, harmonics in the glottal waveform are produced by adducing the vocal folds sufficiently so that they can collide. This changes the waveform from a simple oscillatory shape that has only one frequency. Alternately, or in conjunction with collision, the vocal tract can be engaged to feed back an acoustic wave to the glottal flow.
