Thanks again for your feedback—it’s appreciated! I noticed that your comments focused on a specific element, namely the reference to "a speech (motor) plan execution" difficulty as a type of breakdown in fluency. However, I was actually hoping to get your thoughts on the full mechanism as a whole—as it covers multiple layers beyond just the manifestation level (i.e., the breakdown in fluency). If possible, could you perhaps take a broader look and share any insights or impressions you might have on the entire structure or framework? Also, regarding terminology: I think it might help clarity if we shift from "speech plan execution difficulty" to a more inclusive term like "breakdown of fluency," or even simply "manifestation" which focuses on the observable outcomes (i.e., repetitions, prolongations, and blocks). After all, what ties these primary stuttering behaviors together is that they all reflect an interruption in the forward flow of the intended (desired or planned) utterance.
