An Investigation Of The Airflow Characteristics Of Pulmonary Air Expulsion During Esophageal Speech, Alfred S. Lavorato,

Dissertations and Theses

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. …
