EPG Based Research on Tongue Position and Its Constraint of Word-initial Consonants in Standard Mongolian in China

This paper discusses issues including tongue position, tongue movement space, constraint etc. of Mongolian word-initial consonants. The experimental result shows that word-initial consonant tongue horizontal movement space is constrained by constriction position and is in conformity with the rule that front consonant leads to smaller tongue movement space; higher consonant leads to smaller tongue vertical movement space. Generally speaking, consonants’ tongue vertical variation scope is bigger than tongue horizontal variation scope.
