摘　　要：为研究韵律特征中最能反映语音情感信息的基频参数变化,选取7种典型的情感状态、固定句式,对同一说话人的汉语、英语、日语等多语种语音样本进行基频平均值、基频动态范围、基频抖动等参数的统计分析.统计结果表明,情感语音的基频结构特征随情感状态改变有明显的变化,且不同语种下这种结构的变化有较好的一致性.Pitch averages, pitch ranges and pitch jitters are calculated and statistical analysis of these parameters is carried out to evaluate the differences of the seven multl-typical emotion states. The test sentences are spoken in Chinese, English and Japanese by the same speaker and have the same pattern in syntax. The statistical analysis results show that the pitch structure has distinct diversity with the changes between different emotions and language factor does not effect pitch variation features of some given emotion in multilingual speech obviously.
