蒙古语七个元音声频特性计算机分析

Acoustic features analyses of Mongolian dialects vowels by computer

为了采取语音输入方式来实现蒙古语各类文字文献的自动转换（机器翻译），所选择的语音、语言模型的性能直接影响识别精度。为此对蒙古语各类语言文字的元音进行声学特性的分析和分类不仅对蒙古语语音的识别非常重要，而且对蒙古语的语言学、地方方言学的研究也有很重要的意义．本文介绍对蒙古语哈拉合、察合尔、卫拉特发音元音读音进行声频特性分析的结果以及利用语音模型识别方式验证所测定的不同发音共振峰频率分布情况。

There are many reports of linguistic analysis research of the Mongolian language but researches about acoustic analysis are rare. Scientific explanatiolls about the difference between the phonemes of Oirato and inner Mongoian dialects are especially rare.This paper discusses the acoustic characteristics of Mongoian phonemes and the acoustic differences between the 7 vowels of Oirato and inner Mongolian ill order to realize speech recognition and speech translation of the two languages Results of Formant frequency and Pattern recognition analysis are presented.
