The literature on esophageal speech has identified the problem of extraneous air intake noise, suggested its possible etiology, and provided practical advice for clinical management. Documentation on the efficacy of specific methodology is lacking in the literature. Such documentation would be simplified if objective criteria were used to rate the severity of intake noise. The present study was prompted by the lack of basic data regarding listener evaluation of intake noise.

The purpose of this study was to identify physical and perceptual correlates of acceptability of esophageal air intake noise. A primary and a secondary question were asked:

Are selected objective measures of esophageal speech significantly correlated with sophisticated listener judgments of air intake noise acceptability? The measures used were:

  1. The mean intensity of air intake noise
  2. The mean intensity of speech
  3. The ratio of mean speech intensity to mean intake noise intensity
  4. The number of syllables uttered per intake
  5. The rate of speech (in syllables per second)

Secondarily, are sophisticated listener judgments of overall esophageal speech proficiency significantly correlated with sophisticated listener judgments of air intake noise acceptability?
