To investigate the relationships between objective measures and the results of subjective assessment of voice quality and speech intelligibility in patients submitted to total laryngectomy and tracheoesophageal (TE) puncture.

Retrospective.

Twenty patients implanted with voice prosthesis were studied. After surgery, the entire sample performed speech rehabilitation. The assessment protocol included maximum phonation time (MPT), number of syllables per deep breath, acoustic analysis of the sustained vowel /a/ and of a bisyllabic word, perceptual evaluation (pleasantness and intelligibility%), and self-assessment.

The correlation between pleasantness and intelligibility% was statistically significant. Both the latter were significantly correlated with the acoustic signal type, the number of formant peaks, and the F₂−F₁ difference. The intelligibility% and number of …
