Obtain consistent results with a past version #694

I've upgraded my MFA to version v2.2.12. However, for my downstream task (TTS), my old MFA version (v2.0.0a23) seems to perform better.

What are the major changes since v2.0.0a23 that could affect the performance? In particular, are there any changes in the config which makes it more/less likely to insert a "(blank)"/"sp" token between tokens when aligning?

Are there any changes in the config I could use so that the newer MFA can obtain more similar results to the old MFA?

Many thanks.
