Correlation between tracheoesophageal voice and speech and intraluminal pharyngoesophageal transition pressure*

the good speakers presented the lowest amplitude values of pharyngoesophageal transition pressure during phonation. However, the pressure observed in the rest condition was higher for the good speakers and lower for the poor speakers, suggesting that the raise in the pharyngoesophageal transition pressure during phonation damages the quality of tracheoesophageal communication when using speech prosthesis.
