Strident vowel
Template:Short description Template:Infobox IPA/core1Script error: No such module "Check for unknown parameters".
Strident vowels (also called sphincteric vowels) are strongly pharyngealized vowels accompanied by an (ary)epiglottal trill, with the larynx being raised and the pharynx constricted.[1][2] Either the epiglottis or the arytenoid cartilages thus vibrate instead of the vocal cords. That is, the epiglottal trill is the voice source for such sounds.
Strident vowels are fairly common in Khoisan languages, which contrasts them with simple pharyngealized vowels. Stridency is used in onomatopoeia in Zulu and Lamba.[3]Template:Page? Stridency may be a type of phonation called harsh voice. A similar phonation, without the trill, is called ventricular voice; both have been called pressed voice.Script error: No such module "Unsubst". Bai, of southern China, has a register system that has allophonic strident and pressed vowels.
There is no official symbol for stridency in the IPA, but a superscript Template:Angbr IPA (for a voiced epiglottal trill) is often used.Script error: No such module "Unsubst". In some literature, a subscript double tilde (≈) is sometimes used.[1]
It has been accepted into Unicode, at code points U+1DFD and U+107B4.
