Tonality as Attention: Bridging Human Voice Tonality and AI Attention Mechanisms to Reintroduce the Human Layer to Intelligence

This white paper introduces Tonality as Attention, a unifying framework proposing that human vocal tonality can function as an active attention mechanism within both human and artificial intelligence systems.

Bridging neuroscience, prosody, and computational attention, it argues that tonal cues - such as pitch, rhythm, resonance, and emotional contour - carry structured metadata about salience, empathy, and trust. When computationally modeled, these cues can inform machine attention just as visual or textual embeddings do.

The paper outlines the theoretical grounding, ethical considerations, and practical pathways for integrating tonal cognition into multimodal AI. It connects emotional prosody and AI attention systems, revealing how tone guides focus, empathy and alignment across both human and machine intelligence - reintroducing the human layer to artificial systems through attuned, reciprocal listening and expressive response -  establishing tone as the shared attention signal between human and machine cognition.
