                    元代韵书《蒙古字韵》的声母系统因匣、影、喻(含疑)分化而多出了元代特有的几个声母合、幺、鱼,同时由于知组、照组及非敷的合并又减少了几个声母。多出那几母的分化是源于八思巴字拼写系统及蒙古语的影响;因合并而减少的相关声母,则与《蒙古字韵》所从出的近代韵图《七音韵》中所附"交互音"之类的规定密切相关。而《蒙古字韵》声母系统的保留全浊则又与近代韵图的保守性紧密相联。
                
                The Initial System of Menggu Ziyun had increased Initial He合Yao幺,Yu鱼and decreased Initial Zhao照,Fu敷than Sanshiliuzimu三十六字母.Initial He合,Yao么,Yu鱼are induced from the rules of hP’ags-pa spelling and influence of Mongolia.But the decreasing of Initial Zhao照,Fu敷are complied with Jiaohuyin.In contrast,the voiced initials in the Initial System of Menggu Ziyun had been preserved because of the conservative ideas of rhyme tables.
