Jaw Contribution to the Timing Control of Pharyngeal Consonant Production

Jaw kinematics associated with pharyngeal consonant production in Arabic C1VVC2 utterances were registered and compared with the acoustic duration of corresponding phonetic segments. The results revealed that temporal perturbation due to the effect of the biomechanical constraints characterizing this class of speech sounds is internally compensated for by a strategy adapted by the speaker aiming to control inter-consonantal timing. That is, the degree of adjustment in vowel duration is mainly dependent on the inherent relative degree of jaw height of the surrounding consonants comprising the word. The present findings suggest that 1) the jaw is actively involved in the production process of, not only oral consonants, but also pharyngeal consonants; 2) required temporal re-organization in the utterance due to the presence of a pharyngeal consonant is mainly controlled by the jaw.
