Researchers have introduced StreamChar, a novel framework for generating character audio and video in real-time streaming scenarios. This system decouples long-horizon orchestration from short-window audio-video denoising, utilizing an LLM-based orchestrator for frame-aligned audio conditions and a joint audio-video DiT for local denoising. StreamChar employs a two-stage distillation pipeline for efficient deployment and incorporates mechanisms like a progress-aware pointer and sink-chunk memory to mitigate transcript-audio misalignment and visual drift, achieving real-time performance on a single H100 GPU.
