人声浊音基频测量谱分析算法

Algorithm of Voice Sonant Fundamental Frequency Measuring Spectrum

人声基频检测是一个普遍关心的技术问题,目前所采用的方法也很多。利用数字信号处理的方法,通过对人声的浊音部分进行功率谱分析的方式,采用一种检查共振峰位置,进而遏止共振峰,在频域中凸显基波频率的方法,在频域确定信号的频率,从而自动检查出信号的基频。

Problem about recognition of voice fundamental frequency is popularly cared. Currently, many methods for that is available. By means of methods of DSP, the paper offers a method of recognizing fundamental through analyzing power spectrum, and using methods that check formant in power spectrum. Because of that, the method can find fundamental automatically.
