蒙古语不送气/送气辅音的声学研究

Acoustic Study of Mongolian Aspirated and Unaspirated Consonants

蒙古语中辅音的送气与不送气,向来解释为强弱之分.一般认为[p][k][t]等不送气音和[p‘][t‘][k‘]等送气音的主要区别为前者气流弱后者气流强.针对蒙古语中塞音和塞擦音的送气和不送气现象,提取蒙古语中塞音和塞擦音的声门上压力和气流量,并借实验语音学的方法对其进行对比分析,得出蒙古语辅音不送气/送气的区别,不只是简单的气流、气压的强弱之分,更主要在于辅音除阻段的长度的不同.

The difference between aspirated and unaspirated consonants in Mongolian is usually interpreted as being strong or weak. It is generally believed that the airflow of unazpirated [p] [t] [k] is stronger than that of aspirated[p＇ ][t＇ Ilk＇ ]. With the help of experimental phonetics methods, the article has got such acoustic parameters as over - glottal pressure and airflow amount of Mongolian stops and affricates. Through the comparative analysis, the article holds that the difference between aspiration and unaspiration in Mongolian consonants lies not only in the different amount and pressure of the airflow in obstruction release, but also the time differences in the very release.
