Description
Authors: Team Cap

Date: 4/20/16

Purpose: In this experiment FORCE_ALIGN, VTLN, AND VTLN START were used. This experiment failed do to reasons mentioned below.

Details:
 * Train configuration
 * Corpus: Switchboard
 * Length: 30hr
 * $CFG_FINAL_NUM_DENSITIES = 16 (density)
 * $CFG_N_TIED_STATES = 4000(senones)
 * $CFG_FORCEDALIGN = 'yes' -- required for below
 * $CFG_VTLN = ’yes'
 * $CFG_VTLN_START = 0.70
 * $CFG_VTLN_END = 1.40
 * $CFG_VTLN_STEP = 0.05


 * Timeline
 * Train start: 4:08 PM on 4/26/16
 * Train end: AM on 4/21/16 (Total time: ) (errors in 017.html: )
 * Decode start: on 4/21/16
 * Decode end: on 4/21/16 (Total time: )


 * Decode configuration
 * Decoding on: /mnt/main/corpus/switchboard/30hr/test/trans/dev.trans (~5 hours)
 * Decoding at: 4000 senones to match the senone count in the train configuration

Results: WER: % Unseen

Notes:

017 failed:

Some research (https://sourceforge.net/p/cmusphinx/discussion/help/thread/7c8f824c/?limit=25) led me to believe a possible error would be missing the vtln_align.pl. This is found:

[jax472@miraculix 04.vtln_align]$ pwd /mnt/main/scripts/train/scripts_pl/04.vtln_align [jax472@miraculix 04.vtln_align]$ ls slave_align.pl vtln_align.pl

Plan: Create new experiment (019), copy vtln_align.pl into exp/bin. Retrain.
