Third International Conference on Spoken Language Processing (ICSLP 94)
As in more traditional place-manner models of consonant production, the jaw is not a primary articulator in Browman and Goldstein's Articulatory Phonology, although it does differentiate Arabic "guttural" consonants from the "oral" consonants more commonly seen in the languages of the world. The jaw's role in consonant place of articulation was examined by measuring jaw height in many tokens of VCV sequences with consonants at all places of articulation that contrast in Arabic and French. Results supported the generally secondary role of the jaw in tongue and lip raising for oral consonants. However, the jaw's behavior in strident fricatives did not fit the general picture, and suggests that Articulatory Phonology should be enriched to allow for jaw height to be specified directly in an aerodynamically crucial task for the feature "strident".
