The common vocal sound produced by blocking exhaled airflow (when voicing a vowel) by suddenly closing the vocal tract is called a '(what?) stop'?
Glottal stop Glottal stop The glottal stop is a type of consonantal sound used in many spoken languages, produced by obstructing airflow in the vocal tract or, more precisely, the glottis. The symbol in the International Phonetic Alphabet that represents this sound is . Using IPA, this sound is known as a glottal plosive. As a result of the obstruction of the airflow in the glottis, the glottal vibration either stops or becomes irregular with a low rate and sudden drop in intensity. Features of the glottal stop: In the traditional Romanization of many languages, such as Arabic, the glottal stop is
Vocal cords alone. The larynx is a major (but not the only) source of sound in speech, generating sound through the rhythmic opening and closing of the vocal folds. To oscillate, the vocal folds are brought near enough together such that air pressure builds up beneath the larynx. The folds are pushed apart by this increased subglottal pressure, with the inferior part of each fold leading the superior part. Such a wave-like motion causes a transfer of energy from the airflow to the fold tissues. Under the correct conditions, the energy transferred to the tissues is large enough to overcome losses by
