Fundamental frequency and intensity measurements in laryngeal and alaryngeal speakers.

Fundamental frequency measurements and voice sound pressure levels were examined in 10 tracheoesophageal, 10 esophageal, and 10 laryngeal speakers during three phonation tasks. The results indicated that tracheoesophageal speakers had a fundamental frequency approximately 25 Hz higher than esophageal speakers. Intensity levels for laryngeal and tracheoesophageal speakers were similar. Discussion includes support for this new voice restoration technique.
