pitch detector 中文意思是什麼
pitch detector
解釋
俯仰傳感器-
Taking no account of the non - uniformity of the detector, this paper analyzed the performance of the traditional four - quadrant angle - measurement algorithm and two other algorithms in calculating the pitch angle and the deflection angle of the incident ray, and also compared the error curve of the pitch angle calculated by each algorithm in the full plane
摘要在不考慮探測器非均勻性影響的情況下，本文分析了傳統四象限測角演算法和另外幾種演算法在計算入射光的俯仰角和偏轉角時的性能，還比較了在整個平面內各個演算法得到的俯仰角的誤差曲面。 -
Many methods of pitch detection are developed so far, in this thesis the pitch detector using waveform transform is adopted. according to the problem appearing in pitch extraction experiment, a novel algorithm of pitch detection is presented. the pitch points in speech signal exhibit local maximum across several consecutive dyadic scales, and their positions are similar, so the improved approach selects pitch points by vote strategy, not by traditional method
基頻提取的方法很多，本文採用了小波變換方法，該方法對部分語音得到了較好的結果，但對大部分語音提取的基頻中含有較多錯誤，經仔細分析和研究，本文對它進行了改進，提出了一種基於小波變換的語音基頻檢測新演算法。
