Speech:Exps 0166

Description
Author: Colby Chenard

Date: 17Feb2014

Purpose: The goal of this experiment was to test out different densities values on the 10hr train to optimize WER. This experiment was #3 of six that were done simultaneously(0162,0164,0166,0168,0170,0182) each has the same senone value

but we increased the densities each train, so 8,16,64. I skipped 32 because that was already done by Colby J in previous experiments.

Details: Colby J and I hypothesized that we may get better results as we increase the densities. The downside to this is that the higher the density the longer it takes to decode. I hope that with these experiments that we can get under 30% error rate.
