Next you need to create a new file in your adapt directory called 'adapt.scp'. This file will tell HTK where all your .mfc files (i.e. the speech audio files you converted into HTK '.mfc' format) are located - your file should look like this:
To minimize the problem of multiple pronunciations, you now use HVite (HTK tool) to perform a 'forced alignement' of the phone level transcription of the adaptation data.
Execute the HVite command as follows (remember to change the path to the location of your HTK 3.2.1 install):
$/htk/htk-3.2.1/HVite -A -D -T 1 -l '*' -o SWT -b SENT-END -C
config -H macros -H hmmdefs -i adaptPhones.mlf -m -t 250.0 150.0
1000.0 -y lab -a -I adaptWords.mlf -S adapt.scp dict tiedlist |
This creates the
adaptPhones.mlf
file.
