Hi,

I'm trying to do speaker adaptation using the HTK toolkit. I have Created Tied-State Triphones as per the tutorial in the HTK 3.4 Boo. In Step 13 - Generating the transforms the HHEd command does not create the new hmmdefs and macros. I used the command as follows:

HHEd -T 1 -H am/tiehmm3/macros -H am/tiehmm3/hmmdefs -M am/adapthmm0 config/regtree.hed config/tie.list

My regtree.hed file contains the following:

RN "models"
LS "am/tiehmm3/stats"
RC 32 "rtree"

By running the HHEd command it creates two files named rtree.base and rtree.tree but it does not create the hmmdefs or macros files which I suppose should be created.

I have no idea why this happens. Could someone help me to solve this issue?

Thank you in advance.

I've the same problem. Did you solve it ?

It turned out that only files that are created in this step are rtree.base and rtree.tree

No other files were created.

The "Perform Static Adaptation" section requires the existence of a hmmdefs and a macros file in the hmm16 directory. The command fails because these files aren't present. How did you proceed?

If you are following the HTK book, the command to perform static adaptation is given like this:

HERest -C config -C config.global -S adapt.scp -I adaptPhones.mlf -H hmm15/macros -u a -H hmm15/hmmdefs -z -K xforms mllr1 -J classes -h '*/%%%%%%_*.mfc' tiedlist

There is no mention of a 'hmm16' directory. The hmmdefs an macros shuold be in 'hmm15' directory (Result of the last tied-state HMM training).

If you are reffering to the 'classes' directory, only files that are created in it are rtree.base and rtree.tree

There are no hmmdefs or macros files in the 'classes' directory.

I've been following the VoxForge Adaptation walkthrough, which mentions a hmm16 directory. Would you reccomend following the HTKbook tutorial instead?

What is the HTK version you are using?

And also could you mention the link for the Voxforge Adaptation tutorial?

I'm using HTK 3.4.1, which is part of my problem. The VoxForge adaptation tutorial, step 5 (http://www.voxforge.org/home/dev/acousticmodels/linux/adapt/htkjulius/adapt/step-5) says to use HTK 3.2.1, since there are "issues with adaptation" using later versions. The tutorial asks you to use the HEAdapt function, which doesn't exist in the version of HTK I'm using. I tried to install HTK 3.2.1, but it requires an older compiler that I can't seem to install on my newer Ubuntu.
