Oral pressures, vowel durations, and acceptability ratings of esophageal speakers.
Aerodynamic, acoustic and perceptual measurements were made on a group of esophageal speakers and the results compared to a group of laryngeal speakers. The results indicate that (1) esophageal speakers show significantly higher oral pressure and larger vowel durations for a given phonetic sample when compared to laryngeal speakers and, (2) esophageal speakers who demonstrate oral pressures and vowel durations most like laryngeal speakers are judged to be most acceptable speakers.
