TTS model trained with Montreal Forced Aligner.
To replicate or continue training from the given checkpoint, download LJSpeech,
install MFA
and follow the steps here.
I recommend downloading the pretrained MFA models and running mfa.sh with --train false.
This would help to save time, but one disadvantage is you have to use the MFA g2p for inference (which has a non-standard phoneme set).
