蒙古族短调民歌的呼吸生理信号分析

通过采集蒙古族短调民歌《敬酒歌》的语音和胸腹呼吸生理信号,设计并提取了相关的声学和生理参数,以呼吸周期为单元对此首短调的胸腹呼吸方式进行分析,研究发现:①与言语呼吸相比,短调民歌腹呼吸比胸呼吸提前;②吸气相斜率大于呼气相斜率;③呼气相时长大于吸气相时长,并且都有持续段.本研究为蒙古族短调的研究提供了生理声学分析方法,为蒙古族短调的演唱与保护提供基础数据.

Analysis of Physiological Respiration Signals in Mongolia Short Folk Song

Through capturing the speech,chest and abdominal physiological signals of Mongolian folk short The song of Wining,this article designed and extracted the relative acoustic and physiological parameters.Taking breath cycle as a unit,this paper analyzed the chest and abdominal aspiration pattern of this folk song.Some conclusions have been acquired:① Comparing with speech breathing features,the abdominal signals in Mongolian folk short song appeared earlier than chest signals;②The slope in inspiration phase is larger than that in expiration phase;③Expiration phrase duration is longer than that in inspiration duration,and every circle included a lasting segment.The results of this study provided the physiological and acoustic methods for Mongolian folk short song study and basic data for singing and protection as well.
