鸟鸣叫声特征提取方法的研究

The research on birdsong feature extraction method

鸟鸣叫声的研究和分析方法对开展鸟类学工作有极其重要的作用.通过对鸟鸣叫声进行功率谱分析、声谱分析、Mel倒谱分析和主成分分析,从而对鸟鸣叫声特征参数进行提取,为鸟鸣叫声的个体识别以及鸣叫声与鸟类行为的关系研究提供了有力的技术支持.

The birdsong research and analysis methods are important to develop ornithological study. The FFT analysis, spectrographic analysis, Mel-cepstrum and principal components analysis are introduced in the paper, together with explanations of the birdsong features extraction. It offers technical support for the birdsong individual identification and the research of vocal behavior of birds.
