本研究的目的是(1)建立评价说普通话的人工耳蜗术后儿童声调产生的方法；(2)评价使用这些方法评估声调产生的效果。研究对象包括两组母语为普通话的儿童：14名语前聋儿童接受顺式听力测试，61名听力正常(NH)儿童作为对照。声学分析侧重于量化基于声调省略的词汇声调的分化程度，以及具有顺式的儿童产生的声调轮廓与61名NH儿童产生的标准轮廓的总体相似性。用NH儿童产生的声调表征训练后，用人工神经网络识别顺语症儿童产生的声调。最后，对8名以普通话为母语的NH成人进行了声调产生的知觉判断，以评估这些方法的有效性。结果表明，声学、神经网络和知觉分析的所有测量都高度相关，可以用来有效地评估顺应性儿童的音质产生。(C)2008年美国声学学会。
The aim of the study was (1) to develop methods for evaluating tone production of children with cochlear implants (CIs) who speak Mandarin Chinese and (2) to evaluate the efficacy of using these methods to assess tone production. The subjects included two groups of native-Mandarin-Chinese-speaking children: 14 prelingually deafened children who had received CIs and 61 normal-hearing (NH) children as controls. The acoustic analysis focused on quantification of the degree of differentiation among lexical tones based on tonal ellipses and the overall similarity of tone contours produced by the children with CIs to normative contours derived from the 61 NH children. An artificial neural network was used to recognize tones produced by the children with CIs after trained with tone tokens produced by the NH children. Finally, perceptual judgments on the tone production of both groups were obtained from eight native-Mandarin-speaking NH adults to evaluate the efficacy of the methods. The results showed that all measures using the acoustic, neural-network, and perceptual analyses were highly correlated with each other and could be used to effectively evaluate tone production of children with CIs.
