Im an actor and i want to portray an accurate and respectful stutter

Im an actor and i want to portray an accurate and respectful stutter This isnt for a movie or a tv show, its for a monologue I want to do. I think it would be a good way to add depth to it, I dont actually have a stutter but I want to portray an accurate stutter. I dont want to offend anyone by seeming too over the top with it and seem like im trying to be funny and be insensitive towards a problem that affects real people in their day to day lives. If you have any tips, please let me know in the comments. God bless you all
