What is Open Avatar Chat
Open Avatar Chat is Alibaba's open source modular real-timedigital humandialogue system that supports running the complete functionality on a single computer. Open Avatar Chat supports low-latency real-time conversations (average response latency of about 2.2 seconds) and is compatible with multimodal language models, including text, audio, and video interaction methods. The system is based on a modular design, allowing users to flexibly replace components according to their needs and achieve different functional combinations. Open Avatar Chat provides developers and researchers with an efficient and flexible digital human dialogue solution.
Main Features of Open Avatar Chat
- Low-Latency Real-Time Conversation: The system can achieve low-latency real-time interaction, with an average response latency of about 2.2 seconds, suitable for a smooth conversation experience.
- Multimodal Interaction: Supports multiple interaction methods such as text, audio, and video, providing a rich user experience.
- Modular Design: Adopts a modular architecture, allowing users to flexibly replace components according to their needs, such as automatic speech recognition (ASR), large language model (LLM), and text-to-speech (TTS) modules.
- Multiple Preset Modes: Provides multiple preset configurations and supports different technology combinations, such as local models or cloud APIs.
- Digital Human Avatar Support: Integrates multiple digital human avatar technologies, such as LiteAvatar and LAM (Live Avatar Modeling), and supports 2D and 3D avatar rendering.
Technical Principles of Open Avatar Chat
- Automatic Speech Recognition (ASR): Uses open source or cloud-based speech recognition technology to convert the user's voice input into text, providing input data for subsequent processing.
- Large Language Model (LLM): One of the core components, supporting multimodal language models or calling external language models based on cloud APIs. The model is responsible for understanding user input and generating appropriate responses.
- Text-to-Speech (TTS): Converts the text generated by the language model into speech output, supports local TTS models or cloud services, and enables natural and smooth voice interaction.
- Digital Human Avatar Rendering: Integrates 2D and 3D avatar technologies and, based on real-time rendering technology, displays animation effects driven by speech input to users, enhancing the immersive sense of interaction.
- Modular Architecture: The system is based on a modular design. Each functional module (such as ASR, LLM, TTS, and avatar rendering) can be independently configured and replaced, and users can choose different technology combinations according to their needs.
- Real-Time Communication (RTC): Uses technologies such as WebRTC to achieve real-time transmission of audio and video, ensuring a low-latency interactive experience.
