Esophageal speech

Esophageal speech, also known as esophageal voice, is an airstream mechanism for speech that involves oscillation of the esophagus. This contrasts with traditional laryngeal speech, which involves oscillation of the vocal folds. In esophageal speech, pressurized air is injected into the upper esophagus and then released in a controlled manner to create the airstream necessary for speech.
