Node.js

Examples:

• Mock loop: examples/node-cli
• Composite backend: examples/node-openrouter

bun run examples/node-openrouter/index.ts
# optional: export OPENROUTER_API_KEY=...

import { createVoiceSession } from '@ottervoice/core';
import { createNodeRuntime } from '@ottervoice/runtime-node';
import { createOpenRouterAudioLLM } from '@ottervoice/provider-openrouter';

const runtime = createNodeRuntime();
const session = createVoiceSession({
  mode: 'half_duplex',
  runtime,
  providers: {
    audioLlm: createOpenRouterAudioLLM({
      apiKey: process.env.OPENROUTER_API_KEY!,
      model: 'openai/gpt-audio-mini',
      voice: 'alloy',
    }),
  },
});

await session.start();

Servers can also compose createOpenRouterLLM(), ASR, and createOpenRouterTTS() behind one AudioLLMProvider; the node-openrouter example shows that boundary. Browsers and apps must use the token broker.
