What is CleanS2S
CleanS2S is a streaming speech-to-speech (S2S) interactive agent prototype that provides a high-quality, real-time voice interaction experience. The CleanS2S project is implemented as a single file, simplifying configuration and understanding, making it easy for users and researchers to quickly experience the powerful capabilities of a language user interface (LUI) and explore the potential of the S2S pipeline. CleanS2S supports full-duplex interaction, allowing users and the agent to listen and speak simultaneously, and supports interruption, making conversations more natural. CleanS2S integrates web search and retrieval-augmented generation (RAG) models, enabling the agent to access internet information and provide richer and more accurate answers. The project aims to advance the development of voice interaction technology and is suitable for a variety of practical application scenarios.
Main features of CleanS2S
- Single-file implementation: Integrates the entire voice interaction workflow into a single independent file, simplifying configuration and the process of understanding the project structure.
- Real-time streaming interaction: Uses WebSockets technology to enable real-time voice stream transmission, supporting real-time conversations between users and the agent.
- Full-duplex interaction: Supports users and the agent listening and speaking simultaneously, providing a natural conversation experience similar to that between people.
- Supports interruption: Users can interrupt the agent with new voice input at any moment during the conversation, and the agent will stop current processing and respond to the new input.
- Web search and RAG integration: Based on integrated web search and RAG models, the agent can access and integrate internet information to provide richer answers.
Technical principles of CleanS2S
- ASR (Automatic Speech Recognition): Converts the user's voice input into text.
- LLM (Large Language Model): Processes the converted text and generates the response text content.
- TTS (Text-to-Speech): Converts the generated text response back into voice output.
- WebSockets: Used for real-time streaming transmission of audio and text information, supporting full-duplex interaction.
- Multithreading and queue mechanisms: Ensure that data transmission and processing during streaming do not block.
