目的了解昆曲唱声的频谱特征。方法对14位昆曲不同表演行当发音人的唱声进行长时平均谱分析。结果,在昆曲男、女各行当唱声长时平均谱中5000Hz以下的频段内存在两个包络峰,两个包络峰之间有一个明显的“谷”。谱级最大的包络峰出现在2500Hz以下的低频段,2500Hz以上高频段的包络峰在频谱中出现的频率位置和谱级的大小会因发音人表演行当的不同而表现各异,但这个峰的能量相对很弱。结论:昆曲各行当唱声长时平均谱的谱包络特征是相似的,不同的是包络峰在频谱中的频率位置和谱级;昆曲唱声长时平均谱高频段出现的包络峰不是Sundberg教授定义的歌手共振峰。
Objective To understand the spectral characteristics of Kun Qu Sing. Methods Long-term average spectrum analysis was performed on the phonation of 14 Kunqu opera performance actors. As a result, there are two envelope peaks in the band below 5000 Hz in the long-term average spectrum of the male and female singers in Kunqu Opera, with a clear “valley” between the two envelope peaks. The envelope peak with the largest spectrum level appears in the low frequency band below 2500 Hz. The frequency position and the spectrum level of the envelope peak in the high frequency band above 2500 Hz appear differently due to different performances of the speaker, but this The energy of the peak is relatively weak. Conclusion: The spectral enveloping characteristics of long-term average spectrum of karaoke sing is similar, except that the enveloping peak’s frequency position and spectrum level in the spectrum. The kurtosis peak Not the singer-formant defined by Professor Sundberg.
