Relationship of Intraoral Air Pressure to Tongue Tip-Alveolar Ridge Contact for Lingual Alveolar Stops
Robert E. McGlone, Wendy S Brown · The Journal of the Acoustical Society of America · 1974
Three male speakers were fitted with intraoral air pressure sensing tubes and strain gauge pressure transducers. The transducers were positioned behind the maxillary central incisors. Simultaneous recordings of air pressure and tongue contact were used to determine the relationship between the two during the articulation of /t/ and /d/. The speech samples were VCV utterances constructed using vowels /i/, /a/, and /u/ and words with /t/ and /d/ in the initial, midvocalic, and final positions. Comparison of the resultant curves showed the onset of intraoral air pressure build up coincided temporally with tongue contact with the alveolar ridge. The pressure rise continued until the tongue was withdrawn at which time a rapid pressure drop occurred. This precise relationship was found for all conditions of the study.
