Étude rétrospective longitudinale acoustique et perceptive des voix de substitution après laryngectomie partielle

Abstract : The aim of this longitudinal study was to point out and describe the progress of acoustic and perceptual alteration in substitution voice after four partial laryngectomies. Vocal analysis was performed on 33 patients with different partial laryngectomies, at 3, 6 and 12 months after surgery. Two perceptual scales (GRB & IINFVo) were compared for relevance mean. A perceptual vowel identification test using Praat © was correlated to acoustic analysis of the vocalic triangle to better understand the mistakes. The evolution of the frequency distribution while speaking was explored with the Long Term average Spectrum (LTAS) as well as the temporal parameter (MPT, speech rate). Our results could suggest some hints and recommendations for vocal rehabilitation.
