A perceptual study of utterance samples obtained from 8 skilled esophageal speakers revealed that they were able to accomplish voicing distinction successfully for oral communication. Fiberscopic observation on 4 out of the 8 subjects revealed that there was a transient opening gesture for voiceless sound production at the neo- (pseudo-) glottis which was found in most cases at the highest portion of the reconstructed esophagus. It was assumed that some active tension control mechanism developed around the neoglottis. Sound spectrographic analysis of the speech samples suggested that voice timing played the most important role in voicing distinction for stop consonants, although other acoustical cues should also be taken into consideration.
