Selected acoustic features of tracheoesophageal, esophageal, and laryngeal speech.

Voice samples of 15 laryngeal, esophageal, and tracheoesophageal speakers using the Blom-Singer voice prosthesis were analyzed for intensity, frequency, and rate. Results indicate that characteristic values for tracheoesophageal speech are more similar to laryngeal speech than esophageal speech, demonstrating the powerful advantage of this pulmonary-supported method of alaryngeal voice.
