Node.js 接入

示例：

• Mock 循环：examples/node-cli
• 复合后端：examples/node-openrouter

bun run examples/node-openrouter/index.ts
# 可选：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();

服务端也可以用 createOpenRouterLLM()、ASR 与 createOpenRouterTTS() 实现一个复合 AudioLLMProvider；examples/node-openrouter 展示了这个边界。浏览器 / App 必须走 Token Broker。
