Bidental consonant
Template:Short description Bidental consonants are consonants articulated with both the lower and upper teeth. They are normally found only in speech pathology, and are distinct from interdental consonants such as Script error: No such module "IPA"., which involve the tongue articulated between the teeth rather than the teeth themselves. The diacritic for bidental consonants in the extensions to the IPA is the same superscript plus subscript bridge, Template:Angbr IPA. This is used for sounds most commonly found in disordered speech:
- A bidental percussive, Template:IPAblink, produced by striking the teeth against each other (gnashing or chattering the teeth).
- A voiceless bidental fricative, Template:IPAblink, a fricative made through clenched teeth with no involvement of the tongue or the lips, a "bidental (consonant) produced by air passing through the closed front teeth".[1]
- A voiced bidental fricative, {{errorTemplate:Main other|Audio file "Voiced bidental fricative.wav" not found}}Template:Category handlerTemplate:Category handler, a fricative made through clenched teeth with no involvement of the tongue or the lips and the vocal cords vibrate, due to the sound being voiced.
- Bidental aspiration of another consonant, e.g. Script error: No such module "IPA". or Script error: No such module "IPA"..
People with hypoglossia (abnormally small tongue) may use bidental fricatives for target Script error: No such module "IPA". and Script error: No such module "IPA"..
There is at least one confirmed attestation of a bidental consonant in normal language. The Black Sea sub-dialect of the Shapsug dialect of Adyghe has a voiceless bidental fricative where other dialects have Script error: No such module "IPA"., as in хы {{errorTemplate:Main other|Audio file "xaaa.ogg" not found}}Template:Category handlerTemplate:Category handler "six". It has been transcribed as Template:Angbr IPA, reflecting its value in other dialects, but there is no frication at the velum and it would thus be better transcribed as Template:Angbr IPA. The teeth themselves are the only constriction: "The lips [are] fully open, the teeth clenched and the tongue flat, the air passing between the teeth; the sound is intermediate between Script error: No such module "IPA". and Script error: No such module "IPA".".[2]
