How Are Harmonics Produced at the Voice Source?

by Ingo R. Titze
posted 4 years ago
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.
