Does Screentime Worsen Stuttering?

Does Screentime Worsen Stuttering? Hi, this is my first time using Reddit, and I’m really sorry if I make any mistakes. I started stuttering around five or six years ago. My stutter is more on the moderate to severe side. I just started high school, and today I met with my new speech therapist. She told me that a contributing factor to my stuttering is my screen time. I spend on average six hours online each day. I tried searching for the effects screen time has on stuttering, but I really couldn’t find anything. Maybe I’m just looking in the wrong places, but I’m really curious about this now. I don’t mind cutting back on my screen time, but I just want to know if what she said is true.
