Speech:Exps 0150

Purpose: Attempt to build a language model off the 0148 acoustic model.

Details: Build the LM and then decode.

Results The language model was built without a problem. I tried to run a decode after the LM was built but it failed. This was because I used a separate directory for my acoustic model than I did my LM. When building the LM I created symlinks to the folders in 0148. This created a problem as the decode script tried to access the file /mnt/main/Exp/0150/model_parameters/0150.cd, but because model_parameters is a symlink to 0148, the file is actually called 0148.cd. To remedy this problem, I am creating a symlink in 0148 called LM which points to the language model generated in 0150. There may be a more elegant way to remedy this problem but this appears to have worked for now. The results of the decode are as follows:
