- Résumé : This paper reports the results of a discrimination experiment of acted vs. spontaneous expressive speech by naive listeners. Monoword utterances of 4 French-speaking actors trapped in a Wizard of Oz before simulating in an acting protocol supposed to be optimal for them were extracted from the Sound Teacher/E-Wiz multimodal corpus. Pairs of acted vs. spontaneous stimuli, expressing affective states related to anxiety, irritation and satisfaction were discriminated by 33 French listeners in audio-only (A), visual-only (V) and audiovisual (AV) conditions. 70% of listeners were able to identify acted vs. spontaneous pairs over chance in V, 78% in A and 85% in AV. A strong listener effect confirms the hypothesis of variable competence for separating involuntary vs. simulated affects. Perceived emotional intensity differences appear as a strong cue to discrimination but cannot account for the whole variability.
