Resonant Minds integrates a two-agent conversational avatar in a perception–reasoning–expression loop. HumanOmni-7B summarizes speech, emotion, and expression from the preceding video at 1 FPS. GPT-4o produces a BDIE attribution, belief, desire, intention, and emotion, generates three response candidates, and sends them to three GPT-4o judges for empathy, strategy, and coherence. Index-TTS v2, ElevenLabs backchannels, a CLIP-MLP adapter trained on about 360 synthetic pairs, and DICE-Talk translate the selected response into speech and faces; RIFE interpolates output to 25 FPS. The proposed corpus contains 50 GPT-4o-expanded profiles from manual seeds, 90 scenarios adapted from Sotopia, and 365 VICO/VICOX face-voice pairs. The main evaluation uses only ten cases fixed by seed 2132. Against an Agent baseline that generates one response from text history, Ours improves 16 of 17 automatic metrics; against the omniscient Script condition it improves eight and loses nine. Thus, the abstract's statement that it surpasses Script on key dimensions describes a subset rather than overall superiority. Twenty-two human dialogue raters prefer Script 40.5%, Ours 36.0%, and Agent 23.5%; Ours exceeds Agent on four of five scales, except depth, but no uncertainty or test is reported. For video, Ours leads Open-D, emotion accuracy, and Emo-Score, but not the three synchronization metrics. The user study recruits 85 and, according to the supplement, analyzes 82 after three exclusions; Ours scores highest on emotion 4.50, naturalness 4.34, and quality 3.38, although DICE-Talk is close on naturalness 4.15 and quality 3.29. The evidence does not isolate Theory of Mind. Ours receives multimodal perception, an extra prompt layer, a BDIE analysis, three candidates, and three evaluators; Agent receives one generation. There is no compute-matched best-of-three Agent with the same reranking or equally long deliberation without BDIE labels. The no-ToM ablation reports only Emo-Score, Emo-Acc, and Open-D, not goal achievement, believability, secret preservation, consistency, or human dialogue judgments. Nor are inferred beliefs, desires, intentions, or emotions checked against known states; the section called ToM causal analysis is a selected example. Seventeen automatic metrics are produced by GPT-5 over the same dialogues in three passes, so their standard deviations measure judge variability rather than generation variability. The 30-case OOD test has no baseline or ablation, and modest degradation therefore does not rule out memorization. Human validation also has gaps: the 22-rater protocol and statistics are absent; the video study contradicts 1–5 scales in the paper/table with 0–5 in the supplement, filters participants using a correlation from only three repeated clips, and omits degrees of freedom, intervals, and outcome-specific effects. Personas are GPT narratives from assigned traits, without BFI measurement, behavioral manipulation checks, or documented human validation. The linked repository has one commit, README, and assets and promises code, data, and benchmark later, so full prompts, runs, metrics, and analyses cannot be reproduced. The defensible contribution is an integration prototype suggesting that additional deliberation, candidate selection, and explicit emotion control improve selected metrics and visual ratings. It does not establish correct mental states, human personality, genuine social intelligence, long-horizon stability, or safety for persuasion, social training, or companionship.
Research question
Can a dual-avatar system that feeds back multimodal perception, BDIE attributions, response selection, and emotional expression produce more coherent, strategic, and natural conversations and videos than simple GPT-4o agents or omniscient scripts?
