How to Get More Silence? #630

Closed Moon-sung-woo closed 1 year ago

Moon-sung-woo commented 1 year ago

Hello, first of all, thank you for making a great MFA.

I trained the MFA model for Korean and checked the results, but there is no silence with all spacing units.

Can we get MFA results including more silence?

What parameters should I modify if I can get it?

Thank you.

You can try playing around with the command line options for --silence_probability (I'm not 100% sure if you can affect silence probabilities of trained dictionaries, since there's a lot of per-pronunciation modeling that goes on) and --boost_silence=1.5 or something greater than 1.0.

Oh and also double check that you're on the latest version, there was a bug recently fixed made it seem like there were no silences with --cleanup_textgrids, but --no_cleanup_textgrids showed the silence (https://montreal-forced-aligner.readthedocs.io/en/latest/user_guide/workflows/alignment.html#cmdoption-mfa-align-textgrid_cleanup).
