Perceptual Alignment is an emerging frontier in artificial intelligence - focused on ensuring that AI systems are not only accurate, but correctly understood by the humans who rely on them. As an independent researcher, I collaborate with organizations and institutions committed to building responsible, human-centered AI.

If your work intersects with voice technology, trust and safety, or human–AI interaction, I welcome the opportunity to collaborate with you.

Key Constructs

This research introduces a named vocabulary for perceptual failure in voice-based AI. These constructs are citable, defined, and measurable.

Tonal Contamination

Umbrella Failure Domain

The overarching category of failures in which a voice AI system's tonal or prosodic output undermines accurate human perception and trust.

Tonal Hallucination

Failure Mode

When an AI system produces tonal or prosodic signals that misrepresent the content, confidence, or intent of its output.

Tonal Sycophancy

Failure Mode

When an AI system adopts a tone calibrated to please or affirm the user rather than accurately reflect the information being conveyed.

Ambivalence Blindness

Failure Mode

When an AI system fails to tonally signal uncertainty, producing confident-sounding output in situations that warrant expressed doubt.

Tonal Trust Drift

Failure Mode

The gradual erosion or inflation of user trust caused by cumulative misalignment between an AI system's tone and its actual reliability.

Authority Miscalibration

Failure Mode

When an AI system's tonal register signals a level of authority or expertise inconsistent with its actual knowledge or role.

Perceptual Alignment Error

PAE · Measurement Signal

A proposed metric quantifying the gap between what an AI system conveys tonally and what a human user accurately perceives.

Contextual Authority Index

CAI · Measurement Signal

A proposed metric assessing whether an AI system's tonal authority register is appropriate to the context and content of its output.

Cross-Modal Congruence Score

CCS · Governing Principle & Measurement Signal

The principle that a system's text, visual, and voice outputs should jointly form a unified epistemic signal - reinforcing the same intent and confidence state across every channel and the proposed metric that estimates alignment between vocal prosody and simultaneous visual, textual, or interaction cues.

Regulatory Relevance - This research has direct relevance to emerging regulatory frameworks including the EU AI Act, particularly Article 52 transparency obligations for AI systems that interact with humans through voice. Perceptual Alignment provides an evaluable, measurable standard for assessing whether such systems meet human-centered disclosure requirements.
