This field got reactivated recently, some new models were released (in the order of release, but the last one seems the best at the moment):

1. ZIPA https://github.com/lingjzhu/zipa

2. POWSM https://huggingface.co/espnet/powsm

3. PhoneticXEUS https://github.com/changelinglab/PhoneticXeus

I would be curious to know how to help people to use these models, or what kind of tasks they could be applied to.
