OpenTalking

Project Introduction

OpenTalking is an open-source orchestration framework for real-time digital-human applications. It connects frontend interaction, session state, LLM responses, TTS and voice settings, subtitle events, WebRTC audio/video playback, and local or remote digital-human synthesis backends.

OpenTalking is not a single talking-head model. It sits between product experiences and model services, organizing LLM, speech recognition, speech synthesis, avatar rendering, event streaming, and browser playback into a unified runtime. Developers can start with Mock validation and then move to real models and inference backends such as Wav2Lip, QuickTalk, MuseTalk, FlashTalk, or OmniRT.

It is designed for scenarios such as AI customer support, product demos, course presenters, news anchors, companion characters, and private digital-human deployments. If you are new to the project, start with Quick Start and run the Mock path first. If you are already evaluating models, runtime backends, GPU/NPU resources, or OmniRT, continue with Model Support.

Key Features

• Real-time conversation pipeline: coordinates speech input, LLM response, TTS synthesis, subtitle events, avatar rendering, and WebRTC playback.
• Pluggable model backends: supports backend modes such as mock, local, direct_ws, and omnirt, from local validation to remote inference services.
• Multiple model paths: provides an evolving integration plan for Wav2Lip, QuickTalk, MuseTalk, FlashTalk, FlashHead, and related talking-head models.
• Open LLM/TTS configuration: supports OpenAI-compatible LLM endpoints, including DashScope, DeepSeek, Ollama, vLLM, or internal model services.
• WebUI and command-line tools: use WebUI for session validation, avatar selection, voice configuration, and model status; use CLI entrypoints for service startup and debugging.
• Production-oriented runtime modes: supports local development, Mock validation, Docker, API / Worker split, and external inference-service integration.

User Guide

• Persona Package: import, validate, and run portable digital-human Agent bundles.
• Examples: understand how OpenTalking applies to customer support, product demos, course presenters, and similar scenarios.
• Model Support: review models, runtime backends, and production topology such as Wav2Lip, QuickTalk, FlashTalk, and OmniRT.
• Reference Materials: review benchmark metrics and changelog entries.
• FAQ: troubleshoot installation, configuration, WebRTC, model backend, and runtime issues.
