[P] Are there open-source models related to singing and vocals?

I’m looking to play around with ML models related to speech, particularly singing/vocals. Are there any papers/resources anyone can recommend to get started on creating my own model or open-source models that can be expanded on? The trouble with the models I see online is that they can only change voices given an existing vocals or aren’t open-source, but I’d like to see where it can take text and create vocals in different enunciations. Thanks!
