Intelligibility and Aerodynamic Study of Tracheopharyngeal and Tracheoesophageal Speechs

;;;;

ABSTRACT

Selected characteristics were compared in the speech of three tracheoesophageal, five tracheopharyngeal and ten normal laryngeal adult speakers. Tracheoesophageal speakers use Blom-Singer voice prosthesis after total laryngectomy and tracheopharyngeal speakers use tracheopharyngeal myomucosal shunt after near-total laryngectomy. Intelligibility judgement was based on standard Korean monosyllabic and bisyllabic word lists of 50 items. Aerodynamic study was composed of maximum phonation time, phonaton quotient. phonation pressure and mean air flow rate.
Results
indicate that intelligibility of tracheopharygeal speech is more similar to normal laryngeal speech than tracheoesophageal speech using Blom-Singer voice prosthesis.
