ElevenLabs SDK streaming TTS

Routes the ElevenLabs SDK through allmodels and streams the audio response.

import { ElevenLabsClient } from "elevenlabs";

const client = new ElevenLabsClient({
  apiKey: process.env.ALLMODELS_API_KEY,
  baseUrl: "https://api.allmodels.io/el"
});

const stream = await client.textToSpeech.stream("voice_id", {
  text: "I'm sorry, Dave. I'm afraid I can't do that.",
  modelId: "elevenlabs/eleven-v4",
  outputFormat: "mp3_44100_128"
});

const reader = stream.getReader();
for (;;) {
  const { done, value } = await reader.read();
  if (done) break;
  // Write value to your response, file, or audio playback pipeline.
}

Use native SDK parameters

When the selected SDK matches the provider, pass provider parameters as native SDK fields. Provider preferences are only needed for cross-provider SDK usage.

Providers

Different providers can host the same model. Choose one provider when you need a fixed backend, or let routing select among them.
