This experiment was for replicating the table 17 in the following document. http://www.cavs.msstate.edu/hse/ies/publications/reports/aurora_frontend/2002/report_012202_v21.pdf The difference between the setup for the experiment in the document and the experiment I ran was the number of mixtures. The results I got were much better. The main reason was that I used 8 mixtures. A difference of almost 155 was observed for some sets. The data for training and testing can be obtained from CD's in a folder named AURORA. The feature files, lists and the results are here: /cavs/hse/ies/isip/data/research/nonlinear/exp_011/aurora/asr_wsj_tutorial_v1.4.2/exp_00 The decode_* has the results for different sets, where * denotes the set number. The results obtained are shoen in the table below: /* Table to be added */
