Description
Author: Justin Thibeault Purpose: Determine which parameters were causing decode to fail in 0256.001 Details:

Ran the following command adding the -lw10 -beam and -wbeam parameters. Trying to determine which parameter causes the slave script to fail. Logging to ...0256/001/logdir/decode/001b.log

nohup /usr/local/bin/sphinx3_decode \ -hmm /mnt/main/Exp/0256/001/model_parameters/001.cd_cont_1000 \ -dict /mnt/main/Exp/0256/001/etc/001.dic \ -fdict /mnt/main/Exp/0256/001/etc/001.filler \ -lm /mnt/main/Exp/0256/001/LM/001.lm.DMP \ -ctl /mnt/main/Exp/0256/001/etc/001_test.fileids \ -cepdir /mnt/main/Exp/0256/001/feat \ -cepext .mfc \ -hyp /mnt/main/Exp/0256/001/result/001-1-2.match \ -lw 10 -beam 1e-80 -wbeam 1e-40 \ > & logdir/decode/001b.log &

001c: added the rest of the parameters from the slave script except -ctlcount 0 which appears to tell sphinx3_decode to process 0 utterances (defaults to 1 billion if you don't specify. I couldn't find any documentation saying 0 = infinity).
