摘　　要：目的：探讨声母广度（consonant inventory,CI）和声母（辅音）出现率（percent correct consonants,PCC）在腭裂患儿术后汉语普通话语音发展规律研究中的运用。方法：对同一手术者,同一手术方法,腭裂手术患儿年龄在12-18个月的腭裂术后语音进行随访研究。分别计算术后6个月、1年（最终语音评估年龄均不超过3岁）语料中CI和PCC,并考察腭裂患者与正常儿童间的差异。结果：初次与再次评估时,CI以及PCC间的差异具有统计学意义。与正常同龄儿童语音发展的PCC值相比较,约2岁时（初次评估）PCC差异具有统计学意义,约2.5岁时（再次评估）时差异无统计学意义。结论：腭裂术后特别是2-2.5岁间患儿在语音发展方面获得了显著进步。Objective： To evaluate the consonant inventory（CI） and the percent correct consonants（PCC） in children with cleft lip and palate（CLP） at different postsurgery time. Methods： 28 todders aged 12- 18 months with cleft lip and palate participated in the study. The children underwent an one-stage palatal repair procedure by one surgeon before the age of 18 months. Naming tests were performed in the speech therapy room at the age of 23 and 30 months respectively. Results： PCC and CI were significantly higher in the secondary assessment than in the first assessment for every child. One sample T-test analyses revealed PCC were significantly lower in the CLP group than in the normal peers at 2 years old. There was no statistical difference between 2 groups at 2 and half years. Conclusion： There is a millstone between 2 and 2. 5 years old children with cleft palate repaired in the phonetic acquisition. Further research will focus on the articulation and phonology process of the children.
