【摘要】 本文描述了用混响室中重迭的语言声来测定语言平均频谱的方法,用这个方法测出了汉语普通话的平均频谱.测量结果与自由声提语言噪声的测量结果对比,同时也与由各个元音频谱平均计算出的平均频谱比较,发现几种结果互相符合得很好.由此,给出了普通话的标准频谱以及它的解析表达式.更多还原

【Abstract】 The method for the determination of mean spectral characteristics of speech through analysis of superposed speech samples in reverberation chamber is described and applied to the standard Chinese (putonghua), and the results were compared with those obtained by the method of "speech noise" in free field, and by weighted averaging of standard spectral envelope of vowels. Good agreement was found among them. On this basis, a standard average spectrum of putonghua is proposed and its analytical given.更多还原
