| 摘 要： | 针对基音周期检测实时性的要求,提出了基于小波变换的语音基音周期实时检测算法。该算法利用小波变换极值与信号突变点之间的关系,将小波域波形与时域波形相结合,采取自适应基准、多特征参数提取小波系数极大值,并在2.5 ms时间内捕捉并检测到新的基音脉冲位置。实验表明,该算法对语音和残差信号取得了较好结果。

| Abstract: | This paper introduces a real-time pitch detection algorithm of speech signal used for real-time pitch detection. This algorithm detects pitch pulse in 2.5ms with selected wavelet transform maxima by multi-characteris combining wavelet with time domain waveform, adopting adaptive methods and tic parameters. The results show that the proposed method is suitable for both clean and residual signals. |
