Perceptual characteristics of tracheoesophageal voice produced using four prosthetic/occlusion combinations.
This study examined and compared perceptual characteristics of tracheoesophageal (TE) voice produced using four different prosthetic/occlusion combinations in 15 tracheoesophageal speakers: 1. using the Blom-Singer duckbill prosthesis and digital occlusion of the tracheostoma; 2. using the Blom-Singer duckbill prosthesis and valve occlusion of the tracheostoma; 3. using the Blom-Singer low-pressure prosthesis and digital occlusion of the tracheostoma; and 4. using the Blom-Singer low-pressure prosthesis and valve occlusion of the tracheostoma. Characteristics of speech produced in each condition were also compared to those of 19 normal speakers. Differences in perceptual ratings made by judges who varied in knowledge about laryngectomees were examined. Results revealed a number of speaking parameters that discriminated among normals and the four TE speaking conditions, and that differed according to the judge's expertise level. Clinical implications are emphasized.
