摘　　要：本文概述了唇腭裂序列治疗的历史和腭裂语音的评估方法,归纳了研究中存在的问题。汉语语音的鼻化度研究得出的鼻音与非鼻音临界值,可以作为腭裂语音研究的语言学基础。鼻化度可以作为量化评估腭裂元音鼻音异常等级的标准,元音/i/是一个可以用于腭裂患者临床诊断的敏感音素,其鼻化度可以作为判定腭裂儿童共鸣异常等级及腭咽功能的一个敏感指标,藉此可以提高语音评估的效率和言语治疗水平,改善唇腭患者的生活。语音学方法在障碍语音及临床语音学研究中具有重要意义。Based on the study of nasality of cleft palate vowels,it is pointed out that the nasality degree can be used as a quantitative standard to evaluate the level of hypernasality of cleft palate vowels,and it is emphasized that/i/vowel is a sensitive phoneme for the clinical diagnosis of patients with cleft palate,and that the nasality of/i/can be used as a sensitive index to judge and detect the abnormal level of resonance and velopharyngeal function in children with cleft palate,so as to improve the efficiency of speech assessment,further improve the level of speech rehabilitation treatment of cleft palate patients,and improve their lives.Finally,the importance and clinical diagnostic value of the study of nasality in clinical speech research are expounded.
