초록
The purpose of this study was to analyze spectral versus cepstral measurements in esophageal speakers. The comparisonbetween the measurements in thirteen male esophageal speakers was compared with the control group of thirteen normalspeakers using the sustained vowel /a/. The main results can be summarized as below: (a) the CPP and L/H ratio of theesophageal group were significantly lower than those of the control group (b) the CPP was significantly correlated with thespectral parameters such as jitter, shimmer, NHR and VTI, and (c) the ROC analysis showed that the threshold of 10.25dBfor the CPP achieved a good classification for esophageal speakers, with 100% perfect sensitivity and specificity. Thus, it wasknown that cepstral-based acoustic measures such as CPP, may be more reliable predictors than other spectral-based acousticmeasures such as jitter and shimmer. And it was found that cepstral-based acoustic measures were effective in distinguishingesophageal voice quality from normal voice quality. This research will contribute to establishing a baseline related to speechcharacteristics in voice rehabilitation with laryngectomees.
