摘 要: | 阐述了一种连续语音信号的最高振幅位的基音标注算法,该算法是在声带振动信号中找到喉部振动关闭点,并进行参数调整,从而自动完成在连续语音信号中的基音位置标注。实验证明,该算法能有效地克服以往标注算法中基音周期估计时加倍或减半的误差,从而保证了基音标注的鲁棒性。

A Robust Algorithm for Pitch Marking for Speech Signal Processing |
| |
Abstract: | An algorithm for marking pitch at the location of the largest amplitude of continuous speech signal is described, which is based on the finding of glottal closure instants in laryngograph signal. By adjusting the parameters, the algorithm can find the pitch marks automatically. The experiments show that this algorithm is robust to pitch doubling or halving errors, which are typical problems in automatic pitch detection. |
