Tracheoesophageal speech: With and without tracheostoma valve

Abstract

The tracheostoma valve, developed by Blom and Singer combines the advantages of pulmonary air for phonation with hands-free speech. Patients have anecdotally reported "more normal speech" with the use of the valve. This study was designed to objectively determine if speech acoustic and temporal measures existed between tracheoesophageal puncture using the valve, and those without the valve prosthesis, during speech production among the same subjects. The speech samples of nine male laryngectomees were recorded with and without the valve. Six speech acoustic and temporal measures were calculated and compared under both speaking conditions. No statistically significant differences were found between the two speaking conditions for the six tasks measured. However, other advantages and disadvantages were observed and reported under the valve condition.
