"Reading" instead of speaking helps me

"Reading" instead of speaking helps me tl;dr at the end but I would appreciate it if you read the whole thing A little background information I stutter since I was a little kid, through out my life stuttering wasn't a big problem for me ( or I didn't think it was), but nowadays (I'm 18 now) I started to see the problem and it's giving me a hard time I was desperate for a time, but since I found this subreddit, I gained so much confidence in myself and actually started experimenting techniques to reduce the stutter. Two weeks ago we were making a film for a high school project and I was chosen for on of the main roles (I'm not the kind of person who would let his stutter get in the way of things he love) so I accepted the role. So we were practicing our lines and I was a little bit nervous because I don't want recorded stuttering and then showed to the whole school. But to my surprise my lines were fluent (I said "lines" because they were the only part that was fluent, not my speech outside the scenario), so I'm shooting a scene and in the middle of the shooting I decided to improvise and change the word "Facebook" to "Twitter" but when I tried to say it, it came like (T T T Tw....) and I had a block and couldn't say the word, so I went like "hehe my bad I forgot the line" and I repeated the line again but this time with the original "Facebook" and oddly enough I said fluently without problem. So I realised that when I read something and repeat it it will come out fluent. And now when I'm speaking and feel like I'm gonna stutter on word, I picture it typed in my mind a pretend to read it out loud and I can say this work 90% of the times if not more I don't know if it would work for you guys but it's worth a shot tl;dr :picturing the words typed in my mind and then reading them helps me a lot with speaking fluently.
