This technique uses the body’s natural tissues as the new voice source and requires you to swallow small amounts of air into your esophagus before “belching” them back up. The column of swallowed air causes the food pipe to vibrate, generating the sound that is further modified by the tongue and lips to create words.
Among the three different options for voice rehabilitation, esophageal speech is the oldest method and also the most difficult to learn.
The advantages of esophageal speech are that it is a non-surgical and hands-free method. However, less than 1 in 5 trying to learn the technique will be able to communicate effectively – esophageal speakers typically speak in short sentences that can be hard to understand.
- Non-surgical method.
- Hands-free speech.
- Takes a comparatively long time to learn with intensive therapy needed.
- Low success rate – few learn to communicate well.
- Short sentences – voice quality varies and can be difficult to understand.
An alternative method to esophageal speech is speaking with a voice prosthesis. This method is easier to learn and creates the most natural sounding, fluent, and comprehensible voice.
