Dianxin kexue为了充分挖掘语音信号频谱包含的情感信息以提高语音情感识别的准确性，提出了一种基于小波散射变换和梅尔频率倒谱系数（Mel-frequency cepstral coefficient，MFCC）的排列熵加权和偏差调整规则的语音情感识别融合算法（PEW-BAR）。算法首先获取语音信号的小波散射特征和梅尔频率倒谱系数的相关特征；然后按尺度维度扩展小波散射特征，利用支持向量机得到情感识别的后验概率并获得排列熵，并使用排列熵对后验概率进行加权；最后采用一种偏差调整规则进一步融合MFCC的相关特征的识别结果 ...

Optimizing MFCC Parameters for Breathing Phase Detection
SensorsBreathing phase detection is fundamental for various clinical and digital health applications, yet standard Mel Frequency Cepstral Coefficients (MFCCs) settings often limit classification performance. This study systematically optimized MFCC parameters, specifically the number of coefficients, frame length, and hop length, using a proprietary dataset ...
