Mucosal chatter

The term ‘vocal cord chatter’ describes the audible phenomenon one hears when the voice starts and stops in rapid alternation because the mucosa is at the edge of its ability to vibrate at a given pitch, loudness, and subglottal air pressure. So, it “catches” the airstream and vibrates for a fraction of a second, then stops, then restarts, then stops, etc. The best understanding is gained through audio and video examples.
