面向情感变化检测的汉语情感语音数据库

Chinese emotional speech database for the detection of emotion variations

该文介绍了面向普通话情感变化检测的情感语音数据库CESD。该数据库的语音以对话形式录制,包括男女声情感对话语音1 200段。以生气、着急、中性、愉悦、高兴为基本情感,共包含20种情感变化模式。除语音文件外,还包含带有静音段/有效语音段、情感类别、情感变化段、情感质量等内容的标注文件。为了使更多的研究人员可以使用该数据库,利用P raat工具提取出67维常用声学特征,作为特征文件一同存储在该数据库中。对该数据库进行主观评价和情感变化检测的结果表明:语音情感状态自然、情感变化真实,能够满足语音情感识别和语音情感变化检测研究的双重需求。
