摘  要:为将区别特征应用于语音评测,需分析区别特征应用的可行性及过渡音征对区别特征单音节评测的影响。利用区别特征探针参数并在区别特征决策树中逐层判断的方法进行单音节中声母和韵母的唯一确定,对含过渡音征的语音样本信号与无过渡音征的语音样本信号分别计算声母正检率,两组正检率显著性检验结果显示无显著性差异,因此建议在区别特征单音节检测中不考虑过渡音征。该结果可以为进一步将区别特征应用于普通话语音客观评测提供参考。In order to apply distinctive feature theory in Mandarin evaluation technology,it is necessary to analyze the feasibility of application of distinctive features and effect of initial-to-final transition in detecting syllables.By extracting acoustic parameters and distinguishing layer by layer,the initial and the final in a syllable can be determined uniquely.The detective accuracy of initials in speech samples with initial-to-final transition and speech samples without initial-to-final transition shows no significant difference,so initial-to-final transition is suggested to be ignored in in detecting syllables by distinctive features.The results obtained in this paper can provide a reference for further applying the distinctive features to the objective evaluation of Mandarin.
