一种稳定、精准、实时的语音信号基频的检测与提取算法

Robust, Precise and Real-Time Algorithm for Speech Signal Pitch Detection and Extraction

针对语音基频检测与提取问题,融合了频域算法和时域算法的特点,提出了针对语音基频检测与提取的两步算法,首先基于频域算法的稳定性给出基频的一个粗估计,然后根据时域算法的精确性,再给出一个精确估计。该算法达到了稳定、精准、实时的目标。实验结果表明,该算法在汉语语音基频检测与提取方面的性能优于语音分析与处理专用软件Praat和Adobe Audition的相应功能。

A new two-step algorithm was proposed for speech pitch detection and fundamental frequency extraction. This algorithm first estimates a guess of the pitch based on the frequency analysis, and then calculates an accurate solution for the pitch based on time-domain analysis. This algorithm realized the expectation of robust, accurate and real-time. The experimental results show that the performance of this algorithm is better than that of Praat and Adobe Audition in Chinese speech pitch detection and fundamental frequency extraction.
