OpenAI Realtime API

An OpenAI Realtime API is an API that is a real-time API that can support speech-to-speech processing tasks through low-latency communication.

• AKA: OpenAI Real-Time Voice API, OpenAI Speech-to-Speech API, OpenAI Streaming Voice API.
• Context:
  • It can typically enable Real-Time Speech Processing with native speech-to-speech models.
  • It can typically support Multimodal Input Processing through image input capabilitys and text input capabilitys.
  • It can typically facilitate WebSocket Connections for persistent bidirectional communication.
  • It can typically integrate with Session Initiation Protocol (SIP) for telephony system connections.
  • It can typically provide Natural Voice Generation through emotion-capable voice models like Cedar Voice Model and Marin Voice Model.
  • It can often enable Remote Tool Access through Model Context Protocol (MCP) servers.
  • It can often support Function Calling Capability with JSON parameter passing.
  • It can often maintain Conversation Context across multi-turn interactions.
  • It can range from being a Simple Voice API to being a Complex Multimodal API, depending on its input modality support.
  • It can range from being a Low-Latency API to being a Ultra-Low-Latency API, depending on its response time requirements.
  • It can range from being a Stateless Voice API to being a Stateful Voice API, depending on its context management capability.
  • It can range from being a Single-Language API to being a Multi-Language API, depending on its language switching capability.
  • ...
• Example(s):
  • Voice Application APIs, such as:
    • Customer Service Voice API for automated support tasks.
    • Virtual Assistant Voice API for personal assistant tasks.
    • Educational Tutoring Voice API for interactive learning tasks.
  • Enterprise Voice APIs, such as:
    • Call Center Automation API for high-volume call handling.
    • Telecom Integration API for device upgrade processes.
  • ...
• Counter-Example(s):
  • Text-Only API, which lacks speech processing capability.
  • Batch Processing API, which lacks real-time interaction capability.
  • Traditional IVR System, which lacks natural language understanding.
