Say the same amount of words, but at a slower rate, correct. Do you stutter by yourself by any chance? If you do stutter by yourself, it'll be a great opportunity to practice speaking slower and seeing the effect it has. If you don't stutter on your own, you'll have to practice speaking to others, could be friends or family which is better. https://youtu.be/aTZ5lTniEK8 Got to 1:20 to get to the point of the video. This guy has other techniques which I haven't tried myself but they could help. Best of luck !
