在植入人工耳蜗的语前聋儿童中，音调感知和生产性能高度相关。这一结果与声调感知是良好声调产生的前提这一假设是一致的。先前的研究表明，在使用人工耳蜗的母语非母语儿童中，声调感知和产生存在显著缺陷。本研究的目的是探讨这些儿童的声调知觉和产生的关系。25名植入人工耳蜗的语前聋儿童参加了这项研究。所有受试者均为Advanced Bionics CII/90 K用户，植入物使用时间不同。为了评估音调感知性能，受试者完成了计算机化的音调对比测试。对于音调产生性能，使用人工神经网络来评估从25个受试者中的每一个记录的音调的准确性。在这些受试者中观察到音调感知和生产性能的大的个体差异。音调感知准确度范围为50.0至96.9%正确（机会性能= 50%正确;平均值= 71.0%正确）。音调产生性能的正确率范围为19.4%至97.2%（平均值= 52.0%）。在这组受试者中，声调感知和生产性能之间存在很强的相关性（r = 0.805）。
In prelingually deaf children with cochlear implants, tone perception and production performance are highly correlated. This result is consistent with the hypothesis that tone perception is the prerequisite for good tone production. Previous research has shown remarkable deficits in tone perception and production in native tone languagespeaking, prelingually deafened children with cochlear implants. The purpose of the present study was to investigate the relationship between tone perception and production in those children. Twenty-five prelingually deaf children with cochlear implants participated in the study. All subjects were Advanced Bionics CII/90K users with various lengths of implant use. To evaluate tone perception performance, subjects completed a computerized tone contrast test. For tone production performance, an artificial neural network was used to evaluate the accuracy of tones recorded from each of the 25 subjects. Large individual differences in tone perception and production performance were observed in these subjects. Tone perception accuracy ranged from 50.0 to 96.9% correct (chance performance = 50% correct; mean = 71.0% correct). Tone production performance ranged from 19.4 to 97.2% correct (mean = 52.0% correct). A strong correlation was found between tone perception and production performance in this group of subjects (r = 0.805).
