Training AI agents for audio-visual understanding involves integrating deep learning models that process sound, speech, and visual cues simultaneously. These systems are designed to interpret context, emotion, and meaning across multiple modalities, enabling more natural human–machine interaction. Advances in multimodal transformers and large-scale datasets allow AI to synchronize speech recognition with facial expressions, gestures, and environmental sounds. This makes applications like video summarization, intelligent assistants, and accessibility tools more effective. By learning correlations between audio and visuals, AI agents can achieve a holistic grasp of dynamic media, bridging the gap between perception and contextual interpretation.
