A Volumetric Analysis of the Vocal Tract Associated with Laryngectomees Using Acoustic Reflection Technology.

Objective: Previous studies of the laryngectomized vocal tract using formant frequencies reported contradictory findings. Imagining studies of the vocal tract in alaryngeal speakers are limited due to the possible radiation effect as well as the cost and time associated with the studies. The present study examined the vocal tract configuration of laryngectomized individuals using acoustic reflection technology.
