I think this helps, but it isn't going to stop stuttering. I'm a block-heavy stutter. So if I don't focus on my stuttering and focus on fluency, I find that the number of stutters decreases, but the number of major and severe blocks increases. Because I'm not watching my speech, nasty blocks creep up and can heavily impede me. Either way, stuttering still happens ¯\_(ツ)_/¯
