Unable to update train models in hmm1 directory

[Saisamarth T]

I am trying to initialize and train a set of models on several users using -S. For some reason, after running the script the trained models in hmm1 folder have not been updated. If I delete them, it does not create new ones. Only by using the standard script that trains on 1 user, trained model files are updated/created in hmm1. I am not sure why this is, here is my script:

PROTO=5state
set -x

# initialise each model
for WORD in cat resources/word_list
do

echo Initialising model of ${WORD}

HInit -T 1 \
-G ESPS \
-m 1 \
-C resources/CONFIG \
-l ${WORD} \
-M models/hmm0 \
-o ${WORD} \
-L ${DATA}/lab/train/ \
-S scripts/${FILE} \
models/proto/$PROTO

echo Training model of ${WORD}
HRest -T 1 \
-G ESPS \
-m 1 \
-C resources/CONFIG \
-l ${WORD} \
-M models/hmm1 \
-L ${DATA}/lab/train/ \
-S scripts/${FILE} \
models/proto/$PROTO

done

You are telling HRest to load models/proto/$PROTO whereas it should start with the models just created by HInit, although this won’t actually cause an error in HTK.

Look for an error message from HRest – if it is failing to create any models, it should report an error.

Remember to always wipe all models (from hmm0 and hmm1) before every experiment: this will help you catch errors.

Ah thank you, looks like I forgot to load the initialized models in this script. I didn’t find any error previously, but I can see that the correct trained model files are being written.
