Shifting Relational Paradigms for Affective Computing: Affective Resonance, Vitality Affects, and Vocal Interaction Fields
cs.AI
Quick verdict
Relational-field framework for affective computing with AMI/WavLM Granger proof of concept; sound null calibration, but proxy unvalidated and effects modest.
Summary
The paper argues that affective computing should shift from modeling individual emotional states to treating the 'interactional field' constituted in vocal dynamics as the primary unit of analysis, drawing on Mühlhoff's affective resonance, Stern's vitality affects and contours, and enactivist participatory sense-making; it proposes two design frameworks, ARDO and AARI. As a proof of concept, four-speaker close-talk audio from the AMI Meeting Corpus is processed in 60-second windows; continuous WavLM-Base+ hidden states (12 transformer layers, no quantization) yield an 'expressiveness' statistic residualized against energy. Directional Granger causality (bivariate and 4-speaker conditional VAR) is tested within voice-activity regimes: overlapping speech (Tier A), pooled non-overlap (Tier B), and direction-specific non-overlap (Tier C). Circular-shift nulls reveal severe size inflation in short-series testing (12.8% null rejections at nominal p<.01 for A/macro, a 12.8× inflation), motivating calibrated excess-rejection reporting. Effects are modest: sub-second coupling concentrated in overlap (+6.6 pp bivariate, +7.4 pp energy-controlled at q=5%), near-symmetric across directions, weakening in Tiers B/C. Key limitations: the expressiveness proxy is unvalidated, the method is linear, results are single-corpus, some cells are underpowered (Tier B macro n=18), and no code is released.

Key claims under review
- Affective computing should take the interactional field constituted in vocal dynamics — not individual speaker states — as the primary unit of affective analysis, per Mühlhoff's resonance account, Stern's vitality affects, and participatory sense-making.
- Directional expressive coupling, measured via WavLM-based expressiveness Granger analysis on AMI meetings, is regime-specific: concentrated at sub-second lags under overlapping speech (Tier A) and collapsing under non-overlap conditions (Tiers B/C).
- Short-window VAR/Granger testing suffers severe size inflation (up to 12.8× at nominal p<.01), so directional-coupling claims require circular-shift null calibration.
- Coupling is not reducible to energy synchrony: energy-controlled conditional analysis retains +7.4 pp excess at q=5%, and small cross-feature effects support a multidimensional account.
- ARDO and AARI constitute design frameworks in which affective systems participate in and modulate the interaction field rather than classify individual affect.
Strengths
Null-calibrated inference instead of naive p-values
Table 2 quantifies size inflation on matched circular-shift nulls (A/micro: 11.9% null rejections at nominal p<.05, 2.4×; A/macro: 17.4% at p<.05 and 12.8% at p<.01, i.e. 12.8×), and Sec. 3.3 reports OBS−NULL excess rather than raw rejections — unusually honest practice for short-window VAR/Granger work.
Falsifiable within-corpus negative-control design
The Tier A/B/C regime decomposition (Sec. 3.2) turns the theory into a testable prediction: micro-scale Tier C collapses to 98.4% zero DSS support under Window-BH (Table 1) while Tier A carries the highest non-zero mass, giving a clean empirical contrast without a second corpus.

Scope & Claims
This is an Interspeech-format position paper (cs.AI, Nurobodi, Australia) arguing that affective computing should move from individual-state models — discrete labels or arousal/valence — to treating the 'interactional field' constituted in vocal dynamics as the primary unit of analysis. The theoretical substrate is Mühlhoff's affective resonance [4], Stern's vitality affects and Køppe et al.'s vitality contours [11, 12], and enactivist participatory sense-making [13, 14]. The stated contributions (Sec. 1) are: (1) a null-calibrated directional coupling framework, (2) an interaction-regime decomposition, (3) a multi-speaker conditional analysis, and (4) results on the AMI Meeting Corpus; plus two design frameworks, ARDO (Affective Resonance Dynamic Ontologies) and AARI (Artificial Affective Resonance Intelligence), elaborated in Secs. 2.4 and 4. The central empirical claim: directional vocal coupling is regime-specific — present under overlapping speech (Tier A), weak or absent under non-overlap (Tiers B/C), concentrated at sub-second lags — 'consistent with a relational account.'

Frequently asked questions
What is the main idea of this paper?
It argues that affective computing should model the relational 'interactional field' that emerges when people speak together — rather than classifying each individual's emotion — supporting this with a Granger-causality analysis of WavLM speech features from four-person meetings, plus two design frameworks called ARDO and AARI.
What data and methods were used?
Four-speaker meetings from the public AMI Meeting Corpus, close-talk headset audio processed in 60-second windows. Continuous WavLM-Base+ hidden states provide an 'expressiveness' statistic; directional Granger causality (bivariate and 4-speaker conditional VAR) is tested separately in overlapping vs non-overlapping speech regimes, calibrated against circular-shift null distributions.
What did the study find?
Directional coupling appears mainly during overlapping speech at sub-second lags (+6.6 to +7.4 percentage points of calibrated excess rejections at q=5%) and nearly vanishes when mutual co-presence is removed. The paper also shows naive short-window significance tests are heavily size-inflated — up to 12.8× the nominal false-positive rate at p<.01 — so null calibration is essential.
Is code or data available for this paper?
The AMI corpus and WavLM-Base+ are publicly available, but the paper releases no code and withholds implementation-specific parameters (lag grids, gating thresholds, and the exact expressiveness formula), so exact re-derivation of its figures is not currently possible from the text alone.
