This is my name, and I pronounce it TAH-lee-ah (i.e., rhymes with the flower name, "dahlia"). Can't tell you how many times I've had to correct people: "No, not tah-LEE-ah."
Tahlia Brookins was a contestant on he 12th season of America's Next Top Model, rather famous because she had burn scars all over her torso. She finished 8th out of 13 finalists.
