Speaker Recognition using MFCC and GMM
显示 更早的评论
I've run the system using the following for training: Speech data(NTIMIT) --> MFCC (feature extraction) --> GMM (modeling)
for testing:
Speech data(NTIMIT)--> MFCC (feature extraction) --> EM (scores)
the accuracy I am getting is 44% for 461 speakers. it was confirmed by 2 at least(1. Reynolds. 2. Patra) that running such system should give an accuracy of 60.8% for 630 speakers i have done lots of changes in terms of sampling frequency (mainly 8000 or 16000), number of MFCC cepstums, number of MFCC mixtures and iterations and the window size and that was the best percentage I could get.
I am using an MFCC and GMM codes which gave good result with TIMIT
advice would be really appreciated

i can tell that you should give more attention to the training data and the prepossessing step .... you can use PCA algorithm for dimensionality reduction and the class separability measure i think it may help
and if you can help me with code of the mfcc and the gmm i'll be thankful Regards.

Hi, You can use DTW algorithm for matching the speech files and speaker recognition.

Audio Toolbox provides several examples for speaker recognition (both identification and verification):
