提出了一种基于高斯混合模型(GMM)的倒谱分析方法,将呼吸音分为两类:正常呼吸音和哮鸣音。声音信号被划分为重叠的段,其特征在于通过使用梅尔频率倒谱系数(MFCC)或基于子带的倒谱系数(SBC)的降维特征向量。该方案与其他分类器:矢量量化(VQ)和多层感知器(MLP)神经网络进行了比较。提出了一种后处理方法来改善分类结果。
The cepstral analysis is proposed with Gaussian mixture models (GMM) method to classify respiratory sounds in two categories: normal and wheezing. The sound signal is divided in overlapped segments, which are characterized by a reduced dimension feature vectors using Mel-frequency cepstral coefficients (MFCC) or subband based cepstral parameters (SBC). The proposed schema is compared with other classifiers: vector quantization (VQ) and multi-layer perceptron (MLP) neural networks. A post processing is proposed to improve the classification results.
