Pharyngeal fricatives and affricatives in cleft palate speech due to velopharyngeal incompetence have been considered to be produced in the pharynx. Fluorovideoscopic and fiberscopic examinations in five patients revealed that so-called pharyngeal fricatives and affricatives, as judged on the basis of auditory impression, were both produced at a constriction formed by backward tilting of the epiglottis and elevation of the arytenoid. The velopharyngeal port remained open during production of these sounds but was almost closed during stop and vowel productions. These faulty articulations are adequately termed laryngeal fricatives and affricatives rather than pharyngeal fricatives and affricatives.
