Sažetak
The aim of this study was to analyze the voice quality of alaryngeal tracheoesophageal and esophageal speech, and to determine which of them is more similar to laryngeal voice production, and thus more acceptable as a rehabilitation method of laryngectomized persons. Objective voice evaluation was performed on a sample of 20 totally laryngectomized subjects of both sexes, average age 61.3 years. Subjects were divided into two groups: 10 (50%) respondents with built tracheoesophageal prosthesis and 10 (50%) who acquired esophageal speech. Testing included 6 variables: 5 parameters
of acoustic analysis of voice and one parameter of aerodynamic measurements. The obtained data was statistically analyzed by analysis of variance. Analysis of the data showed a statistically significant difference between the two groups in the terms of intensity, fundamental frequency and maximum phonation time of vowel at a significance level of 5% and confidence interval of 95%. A statistically significant difference was not found between the values of jitter, shimmer, and harmonic-to-noise ratio between tracheoesophageal and esophageal voice. There is no ideal method of rehabilitation and every one of them requires an individual approach to the patient, but the results shows the advantages of rehabilitation by means of installing voice prosthesis.
