摘要

The cepstrum peak magnitude of a/a:/ becomes reduced when either low or high frequency noise increase. In 18 nor- mal subjects and 68 dysphonic patients, perceptual rating according to the GRBAS-system, cepstrum analysis, video- stroboscopic vibration pattern quantification, phonation flow measurement, and multidimensional voice analysis was preformed. Factor analysis demonstrates that the cepstrum peak magnitude indeed is sensitive to aperiodicity of vocal fold vibration as well as to insufficient vocal fold closure and as a relevant acoustic correlate for the G(Grade)parameter of the GRBAS scale.
