Welcome to AIVOCO’s Speech-to-Speech API

Meet ROSE, AIVOCO’s real-time speech-to-speech model that brings voice AI agents to life.
Whether you’re building telecalling agents, AI receptionists, or human-like sales agents, ROSE lets your applications listen, understand, and talk back, all through a natural, continuous speech pipeline. Our APIs and WebSocket infrastructure make it simple to:
  • Create and manage voice agents
  • Connect them to telephony systems or web apps
  • Enable real-time bi-directional audio streaming
  • Transcribe and analyze your calls, instantly.

What You Can Build

With AIVOCO’s Speech-to-Speech platform, you can bring real-time conversational AI to your business or app.

Telecalling Agents

​
How It Works

The AIVOCO Speech-to-Speech flow is designed to be modular and real-time:
  1. Create an Agent — Define your agent’s name, voice, and system behavior via the /agents API.
  2. Connect via WebSocket — Use our secure endpoint to establish a live speech stream between your app or telephony system and ROSE.
  3. Integrate Telephony — Connect with Twilio, Exotel, or any SIP trunking provider using our wss://call.aivoco.on.cloud.vispark.in/ws/{api_key}/{agent_id} WebSocket.
  4. Transcribe Conversations — Retrieve full transcripts and insights from the Transcription endpoint using your call ID.
These steps are covered in detail in the Quickstart Guide →
