| 摘 要： | 为了得到汉语语音关键频率的大体分布情况,提出了应用时频分布的方法来研究。采用了两种途径来分析语音信号:Adobe Audition3.0软件和自制MATLAB软件。两种途径分别得到语音信号的语谱图,通过比较分析,得出结论:绝大部分的汉语语音频率分布范围是0～5 000 Hz。本方法有需要改进的地方,如:能否得到更加细化、更加准确的频率分布情况。

| Abstract: | In order to get the Chinese pronunciations key frequency general distribution,the method based on the time-frequency distribution is presented to research.Two ways to analyze the speech signal are adopted:Audition 3.0 Adobe software and Homemade MATLAB software.The spectrogram of speech signals is obtained by two ways,through comparative analysis,the conclusion that most of the Chinese pronunciations frequency distribution range is from 0 to 5000Hz is reached.Some places of this method are needed to improve,such as:whether more refined and more accurate frequency distribution could be obtained. |
