Communication and Causality

Interpersonal communication is among the commonest of processes, yet a Causal analysis of it in Kant's system seems problematic.  For, Communication entails more than the issuing of a sound and a subsequent neural irritation, as Mechanical Causality is limited to recognizing.  Nor does construing the issuance as 'free' Mechanical Causality, since it does not distinguish a 'boo!' that is merely designed to startle, from a meaningful utterance.  Likewise, conversely, the 'understanding', in Kant's terminology, of a manifold of sounds, does no more than recast them as an 'effect' of which the issuer is a 'cause'.  In contrast, since to 'understand', in the common sense of the term, a message entails a sequence of processes eventuating in a kind of satisfaction, the receiving of a message seems best classified as a 'Teleological Cause'.  Now, any interpretation of an event as 'teleological', in Kant's system, is heuristic, requiring Reflective Judgment.  But, then, Reflective Judgment is itself a processing of data, eventuating in a kind of satisfaction, and, hence, is seems appropriately classified as a 'Teleological Cause', thereby suggesting an infinite regress.  So, at best, it is unclear how Kant's system can accommodate Communication.
