Abstract

The characteristics of esophageal voice render its study by traditional acoustic means to be limited and complicate. These limitations are even stronger when working with patients lacking minimal skills to control the required technique. Nevertheless the speech therapist needs to know the performance and mechanics developed by the patient in producing esophageal voice, as the specific techniques required in this case are not as universal and well-known as the ones for normal voicing. Each patient develops different strategies for producing esophageal voice due to the anatomical changes affecting the crico-pharyngeal sphincter (CPS) and the functional losses resulting from surgery. Therefore it is of fundamental relevance that practitioners could count on new instruments to evaluate esophageal voice quality, which on its turn could help in the enhancement of the CPS dynamics. The present work carries out a description of the voice of four patients after undergoing laryngectomy on data obtained from the study of the neo-glottal wave profile. Results obtained after analyzing the open-close phases and the tension of the muscular body on the CPS are shown.
