La voz del laringectomizado: incapacidad, percepción y análisis acústico

VHI-30 displays similar values in both types of rehabilitated voice. The acoustic analysis shows differences between both types of rehabilitated voices and the usual laryngeal voice. The perceptual study presents a higher degree of affectation on the esophageal voice than on the PF one. There is no relation between what the patient perceives and what the observer values. The acoustic and perceptual studies show closer values to normality in the phonatory prosthesis voice.
