Laryngeal fricative in cleft palate speech.
Some of the substitutions for or [integral of] in cleft palate speech, which was earlier regarded as a pharyngeal fricative, on the basis of listener's judgement, was found to be a laryngeal fricative by means of fluorovideoscopy and nasopharyngofiberscopy. The sound was most likely produced at the stricture between the posteriorly inclined epiglottis and the elevated arytenoids. During the production of laryngeal fricatives, the velopharyngeal port remained open just as for nasal sounds.
