传统的基音检测算法对含噪语音的检测结果较差,本文在线性预测倒谱方法的基础上采用基于线性预测残差倒谱的方法对含噪语音进行基音检测。实验结果表明,该方法使基音峰点更加清晰,提高了基音检测的精度。
The traditional algorithm of pitch detection for the noisy speech has the poor test results. This paper adopts linear predictive residual method based on linear predictive cepstrum to solve this problem. The results show that it makes the peak point more clearly and improves theaccuracy of pitch detection.
