STEP 4 Creating the Transcriptional Files

In this step we create a Master Label File (MLF) - which is a single file that contains a label entry for
each line in our PROMPTS file. We use the script prompts2mlf contained in HTK_scripts directory

perl ../HTK_scripts/prompts2mlf words.mlf prompts
Now, create the mkphones0.led edit script
EX
IS sil sil
DE sp

Next we need to execute the HLEd command to expand the Word Level Transcriptions to Phone Level
Transcriptions - i.e. replace each word with its phonemes, and put the result in a new Phone Level
Master Label File This is done by reviewing each word in the MLF file, and looking up the phones that
make up that word in the dict file we created earlier, and outputting the result in a file called
phones0.mlf This is done by using the Label editor tool HLEd.
cmd> HLEd -A -D -T 1 -l '*' -d dict -i phones0.mlf mkphones0.led words.mlf

This creates the phones0.mlf file.
