舌系带过短的发生率及其与语言清晰关系的调查

Casse study on occurence of ankyloglossi and its effect on pronouncing clarity

舌系带过短的发生率及其对语言清晰的影响在国内外文献中未见有详细报道。舌带系过短究竟会不会影响语音的清晰在学术界中也有不同的看法，作者对三类不同年龄组的３０００名儿童的抽样调查，研究了舌系带过短的发生率及其对语言清晰的关系，发现年龄愈小其发生率愈高，但对语言清晰的影响不大。语言清晰主要和年龄的增长和语言的成熟有关。

Occurrence of ankyloglossi and its effect on pronuncing clarity has not been reported in detail at home and abroad. Academic circles have different opinions on it till now.This article describes the occurrence of ankyloglossi and its effect on pronouncing clarity,based on the sample investigation made on three different age groups children (3, 000 children). It is found that younger children have higher occurrence of ankyloglossi, but which has little influence on pronouncing clarity. Pronouncing clarity mainly depends on the increase of age and the ripe of language ability.
