Abstract: The cepstrum method of speech pitch detection was analyzed carefully, and several shortcomings were pointed out when the method was realized digitally. In order to overcome these shortcomings, a pitch detection algorithm based on digital spectral analysis was presented. It used the power spectrum reprocessing results of speech to extract the pitch contour. The presented method not only overcame the shortcomings of cepstrum method, but also improved the computational speed and the accuracy of the estimated pitch contour.
Key words: pitch detection, power spectrum reprocessing, cepstrum method and pitch contour
摘要: 对基音检测的倒谱法进行了分析,指出其在基音检测计算及其数字实现时存在不足。为 了克服这些不足,提出了一种功率谱二次处理的二次谱基音检测方法,该方法在克服了倒谱法在基音 检测中不足之处的同时还提高了计算速度,基音轨迹曲线估计的准确性也得到了改善。
关键词: 基音检测, 功率谱二次处理, 倒谱法和基音轨迹
