【摘要】 以HSK（高等）口语考试实测录音为研究对象，对比复杂度指标、准确度指标、流利度指标及上述三类指标的二维和三维组合等7组判别变量，对比3个不同容量样本的等级判别结果与专家评分的一致性，考察各项口语能力评价指标的效度。研究结果表明：复杂词比例、Guiraud指标、每50词AS单位数量、单元词语数量、语音准确度、词汇准确度、句法准确度、语速、发音时间比、平均语流长度和百音节更改次数等11项指标，对考生的口语水平具有较好的区分及预测效度；在进行汉语二语口语水平评价时，有必要多维度提取特征并增加样本量。更多还原

【Abstract】 Taking HSK(higher)speaking test recordings as the object of this study,using the consistency of the grade discrimination results of seven sets of discriminant variables,including complexity,accuracy,fluency,and two-dimensional and three-dimensional combinations of the above three types of indexes,three samples of different capacities compared with the ratings of the experts are examined to see how the validity of each of the speaking proficiency evaluation indicators. The results show that 11 indicators,including the proportion of complex words,Guiraud’s index,the number of AS units per 50 words,the number of unit words,phonological accuracy,lexical accuracy,syntactic accuracy,speed of speech,articulation time ratio,average stream length,and the number of hundred-syllable changes,have good discriminating and predictive validity for the candidates’ oral proficiency. It is necessary to extract features in multiple dimensions and increase the sample size when evaluating the oral proficiency of candidates learning Chinese as second language.更多还原
