WebApr 13, 2024 · 模型训练使用已知的语音数据集,在特征向量上训练模型以进行特定任务的预测。最后一步是识别,它将新的语音信号转换为特征向量,并将其输入到训练好的模型中,以预测该声音信号所代表的内容。mfcc算法是一种常用的语音特征提取方法,它通过离散余弦变换(dct)将语音信号转换成一组大小 ... Webspafe.features.mfcc ¶. spafe.features.mfcc. Compute Inverse MFCC features from an audio signal. sig ( array) – a mono audio signal (Nx1) from which to compute features. fs ( int) – the sampling frequency of the signal we are working with. Default is 16000. num_ceps ( float) – number of cepstra to return.
