What is a Glottal Pulse?
Glottal pulse is a term used in the study of linguistics to describe the variances in voice quality affected by the manipulation of the folds of the vocal cords when speaking. In terms of mechanics, a glottal pulse is produced by a flap of tissue in the region of the vocal cords and the gap between them, which is jointly referred to as the glottis. Collectively, all of these areas form the vocal tract. The frequency produced in the glottal pulse results from the vibration of the vocal cords resonating against the larynx. This creates a buzz or hum that lends a distinctive quality to the voice of each individual.
