基于EPG的蒙古语语音研究

Mongolian Phonetic Research Based on EPG

基于动态腭位(简称EPG)的研究给辅音研究带来了新的希望。辅音在语图上的反映是时程短、能量弱,人们很难从语音信号分析中了解辅音的真实面目,而动态腭位能捕捉辅音的瞬间变化,实时地反映它们的重要特征。《蒙古语语音动态腭位数据库》的建立,为蒙古语辅音研究和蒙古语言语进行理论研究创造了良好的条件。在此基础上,人们对蒙古语辅音的发音位置、发音方法、腭化、协同发音等问题正在进行着探索性的研究。目前还急需更丰厚的人力和物力资源来进一步系统地、大力地开展语音实验,对以前的观点和方法"取其精华,去其糟粕",精确地揭示蒙古语发音特征和协同发音规律。

It is hard to know the real character of consonant from the speech signal analysis,but Electropalatography （EPG） can catch the short-termfluctuation of consonant,and show the important characteristic at real time.Inner Mongolia University and the Nationality Institute of Chinese Social Science Academy together build up the Phonetic Electropalatography Database of Standard Mongolian.This large database provides the condition for the study of consonant,synergetic pronunciation.The research method to combine the phonetic analysis will explain the consonant features and synergetic more scientifically and thus provides good condition for the theoretic research of Mongolian language and the consonant acoustic model.In order to more accurately reveal phonetic characteristics and co-articulation rules of Mongolian,currently we still need more abundant manpower and material resources to do the experiment energetically.
