| 摘 要： | 一般语音信号的合成分析是采用LPC参数或共振峰等参数,根据选定的误差准则,调整参数,使得原始语音与合成语音二者误差最小,从中分析语音的有关性质.利用稀疏谱线进行傅立叶反变换来合成元音,提取元音信号频谱中的几根或者几十根谱线进行反变换来合成元音,由试听者进行听辨实验,考察合成语音的清晰度,从频域对语音信号中的信息分布进行探讨.给出了实验结果与结论.

| Abstract: | In order to research relevant properties of speech signal, general analysis of speech signal sythesis adopts LPC parameters or formant frequency parameters to adjust them to get minimum error between natural speech and synthetic speech according to given poinciple of error. By using sparse components of speech spectrum to synthesize vowel through inverse Fonrier Transform, a few components of original spectrum are selected to synthesize vowel. The intelligibility of the synthesized vowels is listened respectively by a few listeners to examine its clarity and the distribution of information in speech signal in frequency domain. The result of the experiment is given and a conclusion is drawn. |
