摘　　要：蒙古语长、短元音的音长能够区别词义,具有系统性的差异,但音长是连续变量,难以找到长短元音在长度上的声学界限。况且,元音音长也会受到语境影响发生复杂变化。本文根据以往研究结论和连续语流中的元音音长统计数据,提出蒙古语元音音长变化规则。主要有:1)元音由于词内位置的不同而出现变化,词首音节元音长,非词首音节元音短;2)出现在词头的元音延长,可当作词界标志之一;3)词首的送气辅音和清擦音会缩短后续元音的音长。There is systematic difference in the length of Mongolian long and short vowels,but the length is a continuous variable,so it is difficult to find the acoustic boundaries of the length of long and short vowels.Moreover,the vowel sound length will also be affected by context.Based on the previous researches and the statistics of vowel length in continuous flow,this paper puts forward the rules of vowel length variation in Mongolian:1)Mongolian vowel length varies depending on their position in the word,i.e.the vowels in initial syllable are longer than the ones in non-initial syllable.This phenomenon is shared by long and short vowels.2)Vowels occurring at the beginning of a word experience vowel lengthening and can function as a marker of word boundary.3)Consonants such as aspirated consonants and voiceless fricatives at the beginning of the word shorten the subsequent vowels.
