Step 5 - Generating the Transforms
Create Regression Class Tree
1. First, create the regtree.hed edit script in your voxforge/adapt directory:
RN "models"
LS "stats"
RC 32 "rtree" |
2. Next create a new hmm16 directory in your voxforge/adapt folder.
3. Then execute the HTK Tool HHEd to build the regression class tree:
|
$/htk/htk-3.2.1/HHEd -H macros -H hmmdefs -M hmm16 regtree.hed tiedlist
|
The new models, together with the regression class tree information, are written to the hmm16 directory:
Perform Static Adaptation
1st pass - global adaptation
1. Execute the HEAdapt command as follows:
$/htk/htk-3.2.1/HEAdapt -C config -g -S
adapt.scp -I adaptPhones.mlf -H hmm16/macros -H hmm16/hmmdefs -K
global.tmf -t 250.0 150.0 3000.0 tiedlist
|
This creates the 
global.tmf
file in your voxforge directory - which is to be used as input into the
second pass.
2nd pass - transform model set
2. Create the hmmAdapt directory
3. Then run HEAdapt once more:
$/htk/htk-3.2.1/HEAdapt -C config -S adapt.scp
-I adaptPhones.mlf -H hmm16/macros -H hmm16/hmmdefs -J global.tmf -M
hmmAdapt -t 250.0 150.0 3000.0 -j 0.9 -i 10 tiedlist
|
this creates 2 files in the hmmAdapt directory:
