基于PAS6600的藏语送气/不送气辅音气流信号研究

Airflow Signals Study of Tibet Aspirated and Unaspirated Consonant Based on PAS6600

文章以藏文字母中的七组送气与不送气辅音为研究对象,利用语音空气动力学PAS6600提取各个辅音的气流信号参数.从呼气时长、平均呼气速度、呼出气流量等三项参数,分析相同辅音的各项参数在不同性别间存在的差异,以及不同发音方法和发音部位的辅音在同一气流信号中的不同表现.发现在藏语中不送气音的呼气时长比送气音大;平均呼气速度的大小从男女平均呼气速度的平均值来看送气音的平均呼气速度比不送气音大;呼出气流量的信号虽受发音方法和发音部位的影响,但主要还是跟发音人的性别有关系,即男性的呼出气流量比女性的呼出气流量要大,这主要跟其生理特征有直接的关系.

This article is about unaspirated and aspirated seven groups of Tibetan consonant.It has implemented aerodynamics PAS6600 parameters.Through expiratory airflow duration,mean expiratory airflow and expiratory volume to analyze the parameters of similar consonant with different gender;the method and place of consonant articulation and it＇s differences with the same Airflow signal.It proved that Tibetan unaspirated expiratory airflow duration is longer than aspirated ones;the aspirated mean expiratory airflow is faster than unaspirated ones.expiratory volume has been affected by the method and the place of articulation.However,gender plays very important role;The expiratory volume of male is much bigger than female which is directly related to physiological characteristic.
