  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.).
