加窗的话,python_speech_features默认不加窗,但提供了调用numpy中窗函数的参数接口,经测试numpy.hanning窗函数和scipy.signal.windows.hann窗函数的数值是一致的,只不过前者为矩阵形式(元素相同的多个向量构成),后者为向量形式。 mfcc = python_speech_features.base.mfcc(signal,samplerate=16000,winlen=0.025,winstep...
Python Speech Features是一个强大的开源库,专门用于从音频信号中提取常见的语音特征,如梅尔频率倒谱系数(MFCCs)和滤波器组能量。对于那些对MFCCs不太了解但想要深入了解的朋友,项目提供了一个详细的MFCC教程。 项目文档详细且易于理解,可访问此处查看。此外,这个项目已发布在PyPI,可以轻松安装和使用。 项目技术分析 该...
