To improve the rates of speaker recognition,a method based on the compressed sensing( CS) is proposed. First,the frame of compressed sensing theory is introduced to analyzing the premise of combining the compressed sensing theory with the speaker recognition. Then the major algorithm of speaker recognition based on compressed sensing is advanced, that is the establishment of speakers’ characteristic database and matrix trace to obtain the maximum average coefficients matching. Oceans of experimental data indicate that this method has strong recognition ability and the performance is good when the collection of speakers is huge.
