Motor Imagery of Speech: The Involvement of Primary Motor Cortex in Manual and Articulatory Motor Imagery
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6579859/> The results have implications for models of mental imagery of simple articulatory gestures, in that no evidence is found for somatotopic activation of lip muscles in sub-phonemic contexts during motor imagery of such tasks, suggesting that motor simulation of relatively simple actions does not involve M1.
Observation-execution matching and action inhibition in human primary motor cortex during viewing of speech-related lip movements or listening to speech
https://www.sciencedirect.com/science/article/abs/pii/S0028393211001801?via%3Dihub> The MEP findings support the notion that observation-execution matching is an operating process in the putative human MNS that might have been fundamental for evolution of language. Furthermore, the SICI findings provide evidence that inhibitory mechanisms are recruited to prevent unwanted overt motor activation during action observation.

It's often less about *what* you want to say and more about how you want to say it to this audience. When Bob and I are talking, it feels like I have little simulations running inside me like Could I say it this way? Could I say it that way? Will that work with Bob? Etc. [†]

(Note I'm not suggesting all internal dynamics are equivalent to talking. Only that the difference between thinking "I have a cat" and saying "I have a cat" is vanishingly small, or at least not as large/distinct most people think it is.)
