Voz a voz en tiempo real con el OpenAI SDK

Envía question.pcm (PCM mono de 16 bits a 24 kHz) como un turno mediante el protocolo OpenAI Realtime y guarda la respuesta hablada en reply.pcm.

import { once } from "node:events";
import { readFile, writeFile } from "node:fs/promises";
import OpenAI from "openai";
import { OpenAIRealtimeWS } from "openai/realtime/ws";

const client = new OpenAI({
  apiKey: process.env.ALLMODELS_API_KEY,
  baseURL: "https://api.allmodels.io/oai"
});
const realtime = new OpenAIRealtimeWS({ model: "eleven_realtime_v1_max" }, client);
const reply = [];

realtime.on("response.output_audio.delta", ({ delta }) => reply.push(Buffer.from(delta, "base64")));
realtime.on("response.done", async () => {
  await writeFile("reply.pcm", Buffer.concat(reply));
  realtime.close();
});
realtime.on("error", console.error);

if (realtime.socket.readyState !== 1) await once(realtime.socket, "open");
const format = { type: "audio/pcm", rate: 24000 };
