  This is the Proceedings of the ICML Expressive Vocalization (ExVo)
Competition. The ExVo competition focuses on understanding and generating vocal
bursts: laughs, gasps, cries, and other non-verbal vocalizations that are
central to emotional expression and communication. ExVo 2022, included three
competition tracks using a large-scale dataset of 59,201 vocalizations from
1,702 speakers. The first, ExVo-MultiTask, requires participants to train a
multi-task model to recognize expressed emotions and demographic traits from
vocal bursts. The second, ExVo-Generate, requires participants to train a
generative model that produces vocal bursts conveying ten different emotions.
The third, ExVo-FewShot, requires participants to leverage few-shot learning
incorporating speaker identity to train a model for the recognition of 10
emotions conveyed by vocal bursts.
