【摘要】：语言是一种物理现象。汉语普通话的平均频谱,是指汉语普通话的发音人以自然状态发音时,长期平均功率谱密度的统计拟合。汉语耳语的平均频谱,是指汉语耳语的发音人以耳语状态发音时,长期平均功率谱密度的统计拟合。本文在前人对汉语与汉语耳语研究的基础上,通过改变录音环境、录音测量设备及数据处理方法、语音阅读材料的选择方法以及语音样本发音人的选择方法等,使用语噪声法,分别采集到160段汉语普通话语音样本与160段汉语耳语语音样本,通过计算分析,分别得到了不同于GB-T7347-1987《汉语标准频谱》的汉语普通话的平均频谱曲线与不同于GB-T7348-1987《耳语标准频谱》的汉语耳语的平均频谱曲线。汉语与汉语耳语可分别应用于产生、传输、接收和处理汉语与汉语耳语信号的系统及电声器件,也可作为其设计依据和模拟信号源的频谱成型依据。
[Abstract]:Language is a physical phenomenon. The average frequency spectrum of Chinese Putonghua refers to the statistical fitting of the long-term average power spectral density when the pronunciation of Chinese Putonghua is in a natural state. The average frequency spectrum of Chinese whispering refers to the statistical fitting of the long-term mean power spectral density when the speaker pronounces in a whisper. On the basis of the previous researches on Chinese and Chinese whispers, this paper uses the method of speech noise by changing the recording environment, recording measuring equipment and data processing methods, selecting the speech reading materials and choosing the pronunciation person of the speech sample, etc. 160 Chinese Mandarin speech samples and 160 Chinese whisper speech samples were collected, and calculated and analyzed. The average spectrum curve of Mandarin Chinese is different from that of GB-T7347-1987 and the average spectrum curve of Chinese whispering is different from that of GB-T7348-1987. Chinese and Chinese whispers can be used to generate, transmit, receive and process Chinese and Chinese whispering signals, as well as electro-acoustic devices, as well as the basis of their design and the spectral shaping of analog signal sources.
