How to Speak by Using Tracheoesophageal Voice Prosthesis

The patient has to take a good breath prior to phonation.  Upon expiration, the thumb need to occlude the end-tracheostomal opening and he will then start to speak.  This act, allow the air from the lungs to be diverted through the tracheoesophageal prosthesis lumen and then directed upwards in the upper oesophagus.  Vibration of pharyngoesophageal segment mucosa produces voice which then converted to words and sentences upon articulation. 

Good pulmonary reserve and control of expiration

allows patient to speak longer with more phonation output.
