The sound characteristics of the crying voices and the sound volume of the nasal resonance of the suckling with the cleft lip and/or palate was investigated, as well as changes in their development. The crying voices of the children who had not been operated on were recorded once a month from their birth to 6 months. (1) Three speech pathologists listened to the recording tapes in which the voices of the children with cleft lip and palate (CLP) with or without feeding plate (Hotz plate) and of the child with cleft lip alone (CLA) in the same age are recorded each, and they decided to which category of the voices the former voices belonged to. (2) The characteristics of the crying voice was investigated by sonagraph phonologically. (3) Nasalance was measured by Nasometer (Kay).Results were as follows : (1) In the audiological experiment the percentage change that the patients gave correct sounds was low until the fourth month. But as they got elder the percentage tended to get higher. (2) The voice in the aspiration and those in the inspiration of the child of CLA clearly made pairing and were rythmical, and the duration time of vocalization in a aspiration is longer than CLP clearly. (3) The nasalance of the children with CLP without Hotz plate was the highest, and nasalance of the child with CLA was the lowest.After the fourth month the difference was seen to increase. The velopharyngeal incompetency seems to influence the production of crying sounds after the fourth month.

本文研究了唇腭裂哺乳期婴儿的啼哭声和鼻共鸣声的声音特征及其在发育过程中的变化。未做手术的患儿从出生到6个月每月记录一次哭声。(1)三位语言病理学家听了记录有或没有喂养板（Hotz板）的唇腭裂（CLP）儿童和同一年龄的单独唇裂（CLA）儿童的声音的录音带，他们决定了前者的声音属于哪一类。(2)用声韵学的方法研究了哭泣声的特征。(3)结果表明：（1）听力学实验中，患者正确发音的百分率变化一直到第4个月才有明显的降低。但随着年龄的增长，这一比例往往会越来越高。(2)CLA患儿吸气声与吸气声配对明显，节奏性强，吸气声持续时间明显长于CLP。(3)唇腭裂患儿无Hotz板组鼻滑音最高，唇腭裂患儿鼻滑音最低，术后4个月后差异增大。第四个月后，咽功能不全似乎会影响哭声的产生。
