Giving my voice model an accent

[EldritchSpiral]

So I'm working on a novel where one of the main characters is a singer and I decided to create a voice model for her so I can hear her sing in her actual voice. I actually have several "voice claims" I want to use, but I have a problem when it comes to her accent, since none of the voice claims have her nationality, and hence, not the accent I'm looking for. So essentially I'm curious is there any way to give my model a specific accent without changing her voice much?

If setting index ratio to 1 doesn't add enough accent, then you'd need someone already singing with the accent. RVC layers a voice on top, it didn't usually do such drastic alterations to the source.

The thing is that for index ratio to work I need my model to have the accent already, which is exactly the problem since none of the voice claims I have for her have the accent I need. Would merging my result model with another voice with the accent be enough? What's the minimum weight a model should have in the merging process to pick up its accent while having mostly the timbre of the other model's voice?
