Date created: 2/17/16

Purpose: Edit sphinx_train.cfg to the new variables and run 125hr_train and examine the results and decode. To reduce our real time factor and word error rate

Details:
 * Set variance normalization to yes.
 * Set senomes to 8000.
 * Set density to 64.
 * Set convergence ratio to 0.001.

2/20/16: Train was finished and created Language model. Made the lm directory than put a trans_unedited file in the lm directory. Prepared transcript. Started decode (1000 files, 8000 senones). Did not make the LM directory correctly so used mv command to change lm to LM. re-executed decode and started decode at 11:30pm.

Results: Decode took 5 hours and 24 minutes. Analyzing the results indicates that the Error rate is 33.9% which did not change very much from the last Error rate which is 35.4%. SYSTEM SUMMARY PERCENTAGES by SPEAKER
