Auto Speech Tech Project2

Baseline

  1. mkdir features in the baseline dir
  2. change the data dir pathToDatabase to yourself in baseline_cqcc.m and baseline_mfcc.m
  3. run baseline_cqcc.m like /matlab_dir/matlab -nodisplay -nodesktop -nosplash -r baseline_cqcc, then do same with the baseline_mfcc.m
  4. u will get cqcc and mfcc features in dir features

NNET

in the nnet dir, we use some deep learning algorithm to solve this problem

Result

the column 3 and 4 only use train data the column 5 use train and dev data to test the eval

BaseLine

system feature EER(Dev) EER(Eval) EER(Eval) Frequency Range B Remarks
GMM cqcc 10.35 30.60 24.77 16-8000 96 Baseline !!!

GMM Approach

only one feature use in the gmm

combine all features in the gmm
