Local real-time talking avatar uses SoulX-FlashHead and LFM3-Audio

By PulseAugur Editorial · [1 sources] ·

A user has developed a real-time talking avatar system that operates entirely locally, utilizing a combination of SoulX-FlashHead, OWSM v4, and LFM3-Audio models. The pipeline first transcribes voice input with OWSM v4, then generates conversational responses and synthesizes speech using LFM3-Audio, and finally animates a portrait in real-time with SoulX-FlashHead. This setup achieves a latency of approximately 850ms on an RTX 5090, though it requires a high-end GPU like an RTX 4090 for optimal performance of the video generation component. AI

IMPACT Enables local, real-time interactive avatar generation, potentially lowering barriers for custom virtual assistants and digital humans.
