Hi! Severe to mild stutterer here. Reading aloud definitely helps but not that much in my opinion. It's best to read aloud in the pace that you normally speak in. For me, it helped when I started reading slowly and gradually increased the pace to my normal speech. I also lowered the pace of my speech when I normally speak by a bit, and took more breaths in between sentences, which all helped me. What I find really helpful is just talking to yourself in front of the mirror about any topic while having eye contact. This builds confidence and also helps you to identify patterns in blocks (if you have any) and you can work on rectifying those patterns. Hope you have a great day :)
