Why aren't there any speech therapies focusing on subconscious fluency? (rather than controlled fluency or auto-pilot speech) *subconscious fluency* = when fluency happens more naturally, exactly like how non-stutterers speak. As explained [here](https://drive.google.com/file/d/1Xg7RwTND-yuIWREJCQJXQpIPoT1cEBSm/view?usp=sharing) *controlled fluency* = fluency that comes from using speech & breathing techniques, or trying to calm down or increase confidence, trying to reduce fear or anticipation, or using distraction methods *auto-pilot speech* = when we’re not actively using techniques, and also not overthinking. But for many of us who stutter, if we only rely on auto-pilot speech, stuttering tends to persist. That is, no stuttering remission. So for stuttering remission to happen, it seems we need to do at least "something". \~\~\~\~\~\~\~\~\~\~ That said—here’s something I’ve been thinking about: No matter which path we take—subconscious fluency, controlled fluency, or auto-pilot speech—we can still use an "acceptance" component into all of them. I mean. if stuttering does suddenly happen, we can stutter openly, calmly, comfortably, and obviously without shame, while walking any of these paths of speaking. So this brings us to the main question: Why do both stutterers and speech therapies, by default, generally close the road on subconscious fluency? I wonder, why is it that both stutterers and therapy kind of... skip over the idea of subconscious fluency? isn't it strange how both we as stutterers and even therapy itself seem to just steer away from the idea of subconscious fluency? as if it’s not an option? subconscious fluency seems to be the one route that almost never gets brought up anywhere! What gives?
