DWT-MFCC Method for Speaker Recognition System with Noise
Fetty Amelia, Dadang Gunawan · 2019
The Mel-frequency Cepstral Coefficients (MFCC) method is the most popular method and has good performance as a feature extraction to date. But based on the simulation results, it is known that the speaker recognition system that uses MFCC as a feature extraction has low accuracy when applied to voice containing noise. So in this study, we propose the DWT-MFCC method to overcome this problem. The simulation results show that the DWT-MFCC method has higher accuracy compare with conventinal MFCC method when applied as feature extraction in the speaker recognition system with SNR from 15 to 40 dB.
