One trick that I do I can quickly restart a sentence and when I get the flow going it makes it easier to say words I struggle with. I'll say "my name is.....(utterly failing to say my name).. my name is JaBeast." idk if this would help you but it helps me. Also sometimes I have to think of a different way to say the thing I want to say without using words I will stutter over. It's like a game except if I lose I don't get to speak lol What do you think? These aren't professional tips or anything just stuff I do.
