I have a question about pronunciation. I've been studying English practically for my whole life, but for some reason I have such a hard time pronouncing the FLAP T. I do know how to make it perfectly, but whenever I try to pronounce it it sounds really forced and whenever I try to talk fast like if I want to say "It was such a pretty day", the 'pretty' word comes up I get so stucked!
Don't even get me started on pronouncing words like turtle, murder, or saying order to. I don't know. I used to practice English like crazy when I was a kid and a teenager and even in adulthood, making the flap T, would be extremely easy, been practicing 3 hours daily for over 5 months with words like murder, turtle and listening to native speakers saying it and repeating it with them".
Still, CAN'T pronounce it properly and fluently. Why? What exercises can help me improving it? Do I need to focus on "tongue exercises"? Jaw exercises, too?
