What is CleanS2S?

CleanS2S is a prototype of a streaming speech-to-speech (S2S) interactive agent, providing a high-quality, real-time voice interaction experience. The CleanS2S project is implemented in a single file, simplifying configuration and understanding, allowing users and researchers to quickly experience the powerful features of Language User Interfaces (LUIs) and explore the potential of S2S pipelines. CleanS2S supports full-duplex interaction, enabling users and the agent to listen and speak simultaneously, and supports interruption functionality for more natural conversations. CleanS2S integrates web search and Retrieval Augmentation (RAG) models, allowing 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 various practical application scenarios.

CleanS2S Main Functions

  • Single-file implementationIntegrate the entire voice interaction process into a single file, simplifying the configuration and understanding of the project structure.
  • Real-time streaming interactionUsing WebSockets technology, real-time voice streaming is achieved, enabling users to engage in real-time dialogue with intelligent agents.
  • Full-duplex interactionIt supports users and intelligent agents to listen and speak simultaneously, providing a natural conversational experience similar to that between people.
  • Support interruptionIf the user interrupts the agent with new voice input at any point in the conversation, the agent will stop its current processing and response to the new input.
  • Web search and RAG integrationBased on integrated web search and RAG model, intelligent body can access and integrate internet information to provide richer answers.

CleanS2S Technical Principles

  • ASR (Automatic Speech Recognition)Converts the user's voice input into text.
  • LLM (Large Language Model): Processes the converted text and generates the corresponding text content.
  • TTS (Text-to-Speech): Convert the generated text response back to speech output.
  • WebSocketsUsed for real-time streaming of audio and text information, supporting full-duplex interaction.
  • Multithreading and queue mechanisms: Ensure that data transmission and processing during the streaming process are not blocked.

Application scenarios of CleanS2S

  • Customer ServiceAs a virtual customer service assistant, it handles customer inquiries and complaints, providing 24/7 uninterrupted service.
  • Smart Home ControlIt can be integrated into a smart home system to control smart devices in the home, such as lights, temperature control, and security systems, using voice commands.
  • Educational SupportAs a language learning assistant, it helps students practice pronunciation, listening, and speaking, providing instant feedback.
  • Health ConsultationIn the healthcare field, it provides basic health consultation and information inquiry services to facilitate communication between doctors and patients.
  • In-vehicle systemIt can be integrated into the vehicle system to provide navigation, entertainment and communication functions, thereby improving driving safety.
