My personal reply #2: The above post said "*It's something about how my brain listens to itself and tries to "fix" my speech before the words even come out.*" In reply. I agree that when brainstorming like this, it's more precise to use the pronoun "my brain" instead of "I". Because no matter what you yourself says or thinks, if the brain still perceives the stimulus (that has not met the conditions) as an error or problem, the speech execution is still prevented or interrupted by the brain even if we don't want it to (or even if we ourselves consciously are not aware of the fear or increased confidence or ANY reason our brain relies on to execute the speech plan). Furthermore. I also agree that the brain (as you elegantly put it) tries to fix speech execution in response to a stimulus, in this case, loud music or a quiet environment. Again, WE (the conscious person) doesn't necessarily have to consciously try to fix it, but the brain aka the subconscious mind is certainly using a predictive algorithm to decide when the speech plan should be executed. This is just my own take on it.
