摘要: Esophageal (SE) and tracheoesophageal (TE) speech are the most commonly used alaryngeal voicing types after total laryngectomy-a surgical procedure of removing a pathological larynx. Both SE TE voices show more aperiodicity than normal laryngeal (NL) voices, vocal characteristics notoriously difficult to extract. The present study investigated difference in among NL, SE, using perception measures nonlinear dynamical analysis. Correlation dimension (D(2)) sample entropy (SampEn) were obtained from 90 voice samples produced by 10 TE, NL male Cantonese speakers. between parameters perceptual ratings different was also examined. Results that both D(2) SampEn values significantly higher for voice. overall judgment quality negatively correlated with SampEn. This finding supports validity assessing quality. indicate analysis could be supplemental tool traditional acoustic analysis, especially analyzing speech.
