Abstract

The purpose of this study was to examine the separate and combined influences of auditory and somatosensory feedback on vowel production. Measurements of the first two formants spoken by male subjects were made at midvowel for the vowel /i/ in four conditions: 1) normal speaking condition, 2) bite block, 3) auditory masking, and 4) bit block and masking. Significant difference were found in each of the experimental conditions. Analyses supported the hypothesis that understood would occur in the masking condition and bite block and masking condition. Undershoot also occurred in the bite block only condition. It was conclude that both auditory and somatosensory feedback influence the production of segmental speech features.
