Esophageal speech
Esophageal speech is a method of speech production that involves oscillation of the esophagus. This method is usually employed by individuals who have had their larynx removed and therefore cannot produce speech in the normal way.
Overview[edit | edit source]
Esophageal speech is a type of alaryngeal speech, or speech that is produced without the use of the larynx. This method of speech production is often used by individuals who have undergone a laryngectomy, a surgical procedure to remove the larynx.
In esophageal speech, air is injected into the upper esophagus and then released in a controlled manner to create sound. This sound is then shaped into speech by the movements of the lips, tongue, and other parts of the vocal tract.
Technique[edit | edit source]
The technique for producing esophageal speech involves several steps. First, the individual must learn to swallow air into the esophagus. This is often achieved through a process known as gastroesophageal reflux, in which air is forced down the esophagus and into the stomach.
Once the air is in the esophagus, the individual must then learn to control the release of this air to produce sound. This is typically done by tightening the muscles of the esophagus and then relaxing them in a controlled manner.
Finally, the individual must learn to shape this sound into speech using the movements of the lips, tongue, and other parts of the vocal tract. This process is similar to the way in which speech is produced in individuals who have not undergone a laryngectomy.
Challenges[edit | edit source]
While esophageal speech can provide a viable means of communication for individuals who have undergone a laryngectomy, it is not without its challenges. Learning to produce esophageal speech can be a difficult and time-consuming process. Additionally, esophageal speech often sounds different from normal speech, which can lead to difficulties in communication.
