Laughter Detection

Laughter detection research aims to automatically identify and analyze laughter in audio and video data, focusing on accurate classification and intensity estimation. Current approaches heavily utilize deep learning models, often employing multimodal fusion of audio and visual features to improve performance, and exploring techniques like transfer learning to address data scarcity. This field is significant for its potential applications in human-computer interaction, mental health monitoring, and even speaker verification, as laughter's unique acoustic and visual properties reveal information about emotional state and speaker identity.
