What path to give as <input_lab_dir> argument in normalize_lab_for_merlin.py?

[harirawat]

I want to create lab files for my voice dataset.

What should be given as <input_lab_dir> argument for running the file https://github.com/CSTR-Edinburgh/merlin/blob/master/misc/scripts/frontend/utils/normalize_lab_for_merlin.py?

Also how to create lab files in this <input_lab_dir>? Any help is appreciated.
