​
Installation

npm install vocode Or, start from our Replit template.

​
Usage

​
Setting up the conversation

Our self-hosted backend allows you to expose a websocket route that operates like StreamingConversation. To get started, clone the Vocode repo or copy the client backend app directory.

​
Environment

Copy the .env.template and add your API keys. 
cp .env.template .env
You’ll need:
  • Deepgram (for speech transcription)
  • OpenAI (for the underlying agent)
  • Azure (for speech synthesis)
DEEPGRAM_API_KEY=
OPENAI_API_KEY=
AZURE_SPEECH_KEY=
AZURE_SPEECH_REGION=

​
Running with Docker

From the client_backend directory: 
docker build -t vocode-client-backend .
docker run --env-file=.env -p 3000:3000 -t vocode-client-backend

​
Running with Python

pip3 install vocode
uvicorn main:app --port 3000
You now have a server with a Vocode websocket route at localhost:3000! You can now use the useConversation hook with your self-hosted backend as follows: 
import { useConversation } from "vocode";

const { status, start, stop, error, analyserNode } = useConversation({
  backendUrl: "<YOUR_BACKEND_URL>", // looks like ws://localhost:3000/conversation or wss://asdf1234.ngrok.app/conversation if using ngrok
  audioDeviceConfig: {},
});
Use the status, start, and stop objects within your React components to control conversations with your self-hosted backend, e.g. 
<>
  {status === "idle" && <p>Press me to talk!</p>}
  {status == "error" && error && <p>{error.message}</p>}

  <button
    disabled={["connecting"].includes(status)}
    onClick={status === "connected" ? stop : start}
  ></button>
</>
