拜读了梁莺等〔1〕撰写的“正常老年人嗓音变化的观察与分析”(简称“梁文”) ,发觉该文中有两处值得商榷。1 关于元音共振峰频率值的正确性元音音色是由声腔的共振决定的。发元音时首先是声带振动 ,产生一准周期性的声带音 ,频谱谐波的频率越高 ,振幅就越小 ,频谱的振幅曲线?
After reading “Observation and Analysis of Vocal Changes in Normal Elderly” written by Liang Ying et al [1] (referred to as “Liang Wen”), I found that there are two issues in the article that are debatable. 1 Correctness of vowel formant frequencies The vowel tone is determined by the resonance of the vocal cavity. Vowel sound when the first vocal cords to produce a quasi-periodic vocal tone, the higher the frequency of the spectral harmonic, the smaller the amplitude, the amplitude curve of the spectrum?
