A glottal stop or glottal plosive is a type of consonantal sound used in many spoken languages, produced by obstructing airflow in the vocal tract or, more precisely, the glottis. It is familiar to English-speakers as the catch in the middle of "uh-oh". The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʔ⟩.

As a result of the action of the glottis, glottal vibration either stops or becomes irregular with a low rate and sudden drop in intensity.
