A quantitative description of the segmental errors occurring in the speech of deaf children is developed. The method of description separates out those errors or characteristics that are common to all deaf speakers from those that are common to different subpopulations of the deaf (e.g., severely versus profoundly hearing impaired) from those errors or characteristics that are unique to individual speakers. Using this technique, the pattern of segmental errors is specified for several groups of children including deaf children at a school for the deaf as well as hearing-impaired children who have been mainstreamed into the regular school system.
对聋儿言语中出现的音段错误进行了定量描述。描述方法将所有聋人共有的错误或特征、聋人不同亚群体（如重度与极重度听力受损）共有的错误或特征以及个别说话者特有的错误或特征区分开来。运用这项技术，为几组儿童确定了音段错误模式，其中包括一所聋校的聋儿以及已融入常规学校系统的听力受损儿童。
