Just what the title asks.
Having grown up in Quebec, Canada, I speak both English and French. Despite that, I never really mastered rolling my Rs. The closest I can get is a sound similar to the ch in achos. That isn’t much of an issue in French, since there isn’t a ch sound to confuse it with, but I would like to get a little closer to the actual sound for Welsh.
I realize that it isn’t a huge issue since I would likely be understood regardless, but if I can find a way to get it right, why not?
