摘要
耳语音的声学特征是研究其语音识别和说话人识别的重要组成部分。介绍了耳语音的特点并讨论了其声学特征。由于耳语音没有基频,所以共振峰与音长特性可以作为重要的声学参数用于识别。对汉语6个耳语音元音进行了分析研究,证明共振峰频率和音长可以作为耳语音识别的特征参数。
Study on the acoustic characteristic is important to speech and speaker recognition in whispered speech. In this paper, the characteristics of whispered speech are introduced and the acoustic features in Chinese whispered speech are discussed. There is no fundamental frequency in the whispered speech, so other features, such as the duration and formant are extracted and analyzed. From the experiments with six simple Chinese whispered vowels, it is proved that the duration and the frequency of formant can be used as the main acoustic features in the Chinese whispered recognition.
