Description
Authors: Team Cap

Date: 4/07/16

Purpose: Testing the effect of lower convergence ratio (from .04 to .004). Previous test have shown us this increases WER. Also testing the effect of setting varnorm to “yes”, a previous experiment has shown a 2.8% WER increase over a 5 hours corpus.

Details: CONSIDER UNUSEABLE Two parameters (convergency_rae and VARNORM) were changed in respect to the baseline experiment (003). It is unclear what affected the results.

 * Decoding at: 4000 senones to match the senone count in the train configuration

Results: WER: 27.4%
