I have a mild, mainly anxiety driven and psychological stutter. I have a few tricks. It’s weird because one trick will work great one day and another day it will be useless. So some of the tricks I learned in speech therapy that help are. Slowing down. Yes everyone says to do this and doesn’t always work, but slowing down and pacing yourself can be beneficial especially when trying to explain something to someone. Easy onset. If you are like me, you have a hard time saying the starting letter or few letters of words most of the time. Try to gently say the first sound, it releases tension in your mouth that causes blocks or repetition. Linking words. Along with the first letter problem, linking words is where you take 2 words and say them both consecutively. So if you are trying to say ‘one hour’ for example, instead of separating them try saying them consecutively like they are not 2 words but one word. This one takes practice and isn’t easy but once you learn it can help in certain situations. Rhythm speaking. This one is also tricky for me. It is where you focus on the flow and pace of your speech rather than individual words. Goes along with speaking slowly. Some triggers I have are thinking about my stutter, poor sleep, not exercising or eating well, and stress/anxiety.  Mine is weird in that it will be amazing for a bit then the next day or week will be terrible. Still figuring out my triggers and what helps, one thing I find that helps is having a creative output. It takes your mind off of it and can get you in a flow state of what you are doing. Try not to dwell on your speech as it will only make it worse. Hope this helps at all, good luck.
