RESUMO
OBJECTIVES: The aim of the study is to determine the accuracy of acoustic spectrography as an outstanding tool in the characterization and monitoring of esophageal voice. MATERIAL AND METHODS: Our subjects were comprised of 33 laryngectomized patients (all male) that underwent qualitative acoustic (spectrography of vowel /a/ and a sentence), quantitative acoustic (phonation time, fundamental frequency, maximun intensity sound level, speech rate) and perceptual protocol. RESULTS: There is a significant statistical relationship among Yanagihara-like spectrographic chart classification, psycho-acoustical perception and quantitative acoustic parameters. CONCLUSION: We consider that acoustic spectrography is an easy, effective method for studying esophageal voice, seeking for improving oral communication skills and rehabilitation in the laryngectomee population.
