Comparison between the classification based on features and percentage of correct consonants in speech disorders

PURPOSE: to observe the differences between the ratings of severity of phonological disorders obtained by Percentage of Correct Consonants-Reviewed and the classification based on qualitative traits. METHODS: data were collected on pre speech therapy 38 subjects in their phonological systems were classified according to the quantitative assessment of Percentage of Correct Consonants-Reviewed (Mild, Mild-moderate, Moderate-severe, Severe deviation) and qualitative assessment based on features (Mild, Moderate, Moderate-severe, Severe deviation). Data were analyzed by frequency tables and through the chi-square test statistical (p研究目的：本研究旨在对比基于修订版正确辅音百分比（Percentage of Correct Consonants-Reviewed）量化评分所得的语音障碍严重程度评级，与基于定性特征的分类结果之间的差异。 研究方法：本研究收集了38名言语治疗前受试者的数据，分别通过修订版正确辅音百分比（分级为轻度、轻中度、中重度、严重偏差）的量化评估，以及基于特征的定性评估（分级为轻度、中度、中重度、严重偏差）对其语音系统进行分类。随后采用频数表及卡方检验对数据进行统计分析（p
