The Differences in Prosodic Features of Alaryngeal Speech after Laryngectomy

 

Abstract

Purpose: Defining the prosodic features of alaryngeal speech and determining their differences depending on the type of alternative speech.

Methods: The study included 60 laryngectomized subjects of both sexes with a mean age of 63 years. The subjects were divided into three groups depending on the type of alternative alaryngeal speech. Prosodic features were assessed using a four-component scale for the assessment of prosody of alaryngeal speech by three examiners. Statistical data processing was done using the SPSS statistical package.

Results: Significant differences were found between tracheoesophageal, esophageal, and electro laryngeal speech with respect to melody and accent performance, and variable rhythm, while the existing differences in the realization of pauses in speech were not significant. Most tracheoesophageal subjects have the appropriate melody, as well as the accent achieved during the speech, the logical pauses present, and in most cases the appropriate speech rhythm.

Conclusion: By evaluating prosody, vocal rehabilitation by the installation of a tracheoesophageal prosthesis has proven to be the most optimal rehabilitation method.
