The glottal stop, or more fully, the voiceless glottal plosive, is a type of consonantal sound used in many spoken languages. In English, the feature is represented, for example, by the hyphen in uh-oh! and by the apostrophe or ʻokina in Hawai i among those using a preservative pronunciation of that name. The glottal stop is produced by obstructing airflow in the vocal tract. The symbol in the International Phonetic Alphabet that represents this sound is ʔ. It is called the glottal stop because the technical term for the gap between the vocal folds, which is closed up in the production of this sound, is the glottis. |
