Abstract

The general purpose of this investigation was to specify further the activity of the pulmonary tract in esophageal speech. Specifically, the study sought to determine whether pulmonary airflow (PAF) rate varied in continuous speech as a function of manner of production, voicing, syllabic position, and perceived level of stoma noise. PAF rate variation was defined as the frequency and magnitude of changes occurring in association with the variables of this study.

Six esophageal speakers utilizing the inhalation method of air intake were classified as high or low stoma (pulmonary) noise speakers on the basis of ratings by three speech pathologists. The /p, b, s, z/ phonemes were placed in arresting and releasing syllabic positions of single syllable words which were combined with other words to comprise two word phrases. The resulting eight phrases were uttered three times in random order by each speaker, while PAF rate was monitored at the tracheastoma, and recorded simultaneously with the phrases on the graphic printout.

The graphic printout of the PAF rate curves revealed that air flowed from the stoma continuously throughout the phrase for each phrase and each speaker, but showed no fluctuations in rate within phrases for any of the variables of the study. Additionally, it was noted that PAF rate was not associated with perceived level of stoma noise.
