蒙古族短调民歌的呼吸生理信号分析

Analysis of Physiological Respiration Signals in Mongolia Short Folk Song

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.

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.
