Speech produced by trapping air in the esophagus and forcing it out again. It is used after removal of a person's larynx (voice box).

Voice and speech rehabilitation following laryngectomy

The first aim of this study is the compilation of the various methods of voice and speech rehabilitation following laryngectomy. Therefore, this book gives a detailed survey of these voice rehabilitation methods, with emphasis on the tracheo-esophageal shunt method with a valve prosthesis in respectively Chapter II, Chapter III and Chapter IV. The development of these valve prostheses, which are inserted into a surgically created tracheo-esophageal shunt, has presented a giant step forwards in the voice and speech rehabilitation of laryngectomees.

The Role of Esophagus in Voice Rehabilitation of Laryngectomees

The total laryngectomy is a standard procedure of laryngeal carcinoma treatment which leaves multiple persistent consequences on a laryngectomized person. After laryngectomy, all of patients cannot speak loudly, and 10–58% patients have a dysphagia. In such changed anatomical condition, the esophagus has a key function in two of three primary approaches to voice—speech rehabilitation of laryngectomized patients: esophageal and tracheoesophageal speech therapy method because one of these is the only acceptable solution of substitute alaryngeal speech.
