Research on Robust Speaker Recognition Parameters Based on Compressed Sensing
摘要
Abstract
Speaker recognition under Nyquist sampling has got a large amount of data in order to ensure a high recognition rate,resulting in a waste of sampling resources,and compressive sensing theory can solve this problem. Based on compressed sensing theory,it makes use of ladder observation matrix projection in this paper. When the compression ratio is 1:2,the system ensures the recognition rate,so that the sample data is reduced to half. Under noisy environment,spectral subtraction is applied in compressed sensing and feature extrac-tion,and feature parameters are extracted directly from estimated clean speech power spectrum CS-SSMFCC (Compressed Sensing Spec-tral Subtraction Mel Frequency Cepstral Coefficient) . Experimental results show that compared with the traditional identification parame-ter MFCC (Mel frequency Cepstral Coefficient),CS-SSMFCC based on spectral subtraction under CS framework can effectively im-prove the robustness of the system,with good anti-noise performance.关键词
