Try slowing down and also maybe make a beat or rhythm in your head. Sometimes I find that if I make a rhythm in my head or even tap my thigh or fingers, I’m able to slowly get my words out along with the rhythm or beat. They say most people dont stutter when they sing and I think it has something to do with that. Maybe catching your flow or something. Regardless, take your time dude, I know it can be rough. It takes time and understanding how your speech therapy work, as some methods work for some and don’t for others. Look luck on your journey!
