一、MFCC概述 在语音处理领域里,梅尔频率倒谱(mel-frequency cepstrum简称MFC)表示一个语音的短时功率谱,是一个语音的对数功率谱在频率的一个非线性梅尔刻度上进行线性余弦转换所得。 所有的梅尔频率倒谱系数(Mel-frequency cepstral coefficients 简称MFCC)共同的组成一个M... ...
Mel-frequency cepstral coefficients (MFCCs) are a widely used feature representation in speech and audio signal processing. They are derived from the mel-frequency cepstrum, which itself is based on the mel-frequency scale. Here's a breakdown: 1.Mel Scale: The mel scale is a perceptual scale ...

The aim of this paper is to show the accuracy and time results of a text independent automatic speaker recognition (ASR) system, based on Mel-Frequency Cepstrum Coefficients (MFCC) and Gaussian Mixture Models (GMM), in order to develop a security control access gate. 450 speakers were ...
The superior performance of the mel-frequency cepstrum coefficients may be an attributed to the fact that they better represent the perceptually relevant aspects of the short-terms speech spectrum... R Mal,RK Sharma,N Kumar 被引量: 2发表: 2014年 Speaker Recognition using VQ and DTW Linear Pred...
Boosting Speech/Non-speech Classi.cation Using Averaged Mel-Frequency Cepstrum Coefficients Features AdaBoost is used to boost and select the best sequence of weak classifiers for the speech/non-speech classification. These weak classifiers are chosen the simple threshold functions. Statistical mean and...
