Abstract
Measures of lingual pressures which occurred during syllable utterances by 10 young adults were recorded superior and lingual to the left and right maxillary first molars and central incisors by strain gauge pressure transducers. These recordings were obtained during fast and slow utterance rates of selected consonant-vowel and vowel-consonant syllables. Measurement of these recordings showed: (1) mean peak lingual pressure varied depending upon the consonant and its position in the syllable; (2) peak pressures obtained from the molar region were less variable and generally greater than found in the central incisor region; (3) integrated time pressure values for entire syllables showed no appreciable difference at different transducer positions; and (4) greater integrated time pressure measures as well as greater variability was found for syllables repeated rapidly compared to slower utterances.
