Proceedings of the ACII Affective Vocal Bursts Workshop and Competition 2022 (A-VB): Understanding a critically understudied modality of emotional expression
share
This is the Proceedings of the ACII Affective Vocal Bursts Workshop and Competition (A-VB). A-VB was a workshop-based challenge that introduces the problem of understanding emotional expression in vocal bursts – a wide range of non-verbal vocalizations that includes laughs, grunts, gasps, and much more. With affective states informing both mental and physical wellbeing, the core focus of the A-VB workshop was the broader discussion of current strategies in affective computing for modeling vocal emotional expression. Within this first iteration of the A-VB challenge, the participants were presented with four emotion-focused sub-challenges that utilize the large-scale and `in-the-wild' Hume-VB dataset. The dataset and the four sub-challenges draw attention to new innovations in emotion science as it pertains to vocal expression, addressing low- and high-dimensional theories of emotional expression, cultural variation, and `call types' (laugh, cry, sigh, etc.).
