I started stuttering when I was 6-7 years old. I always had mild to medium stutter and now I'm 24. After I started reading aloud and practiced meditation, my stutter has reduced drastically. Need a pro tip? Whenever you make a call or whenever you are in a situation where you stutter most, just admit to other person that you stutter. It will reduce your stutter. Avoid words that make you stutter and also practice some vocal exercises and lip trills along with meditation. to relax your mind. Hope I helped. And remember your stutter will never be cured but it will reduce over time(people will hardly notice) if you really want to.
