You have a voice clip in English and want it in Spanish — not subtitles, actual spoken audio. Your agent transcribes the clip, translates the text with context-aware AI, then synthesizes a natural voice reading it back in the target language. ~$0.14, end to end — audio in, audio out.
This is a durable MPP demo — every leg needs a real model: real transcription, real translation, real voice synthesis. A sandboxed client can’t fake any of them. The artifact (the re-voiced clip) is re-hosted on our store, so the URL is durable.

​
The prompt

Take this English clip and give me a Spanish version I can play:
https://example.com/clip.mp3
Use fal Whisper to transcribe, DeepL to translate, and ElevenLabs to read it back.

​
What runs

  1. POST /fal/fal-ai/whisper — transcribe the source clip to text (~$0.02)
  2. POST /deepl/v1/translate — translate the transcript, context-aware (~$0.02)
  3. POST /elevenlabs/v1/text-to-speech/:voiceId — synthesize the translated voice (~$0.10)

​
Run it

​
Claude Desktop (MCP)

npm install -g @t2000/cli && t2 init && t2 receive && t2 mcp install
Paste the prompt with any audio URL and target language. The agent chains the three calls and hands back the new clip’s URL.

​
SDK

import { T2000 } from '@t2000/sdk';

const agent = await T2000.create();
const sourceUrl = 'https://example.com/clip.mp3';
const voiceId = '21m00Tcm4TlvDq8ikWAM'; // any ElevenLabs voice

const transcript = await agent.pay({
  url: 'https://mpp.t2000.ai/fal/fal-ai/whisper',
  method: 'POST',
  body: JSON.stringify({ audio_url: sourceUrl }),
});

const translated = await agent.pay({
  url: 'https://mpp.t2000.ai/deepl/v1/translate',
  method: 'POST',
  body: JSON.stringify({
    text: (transcript.body as { text: string }).text,
    target_lang: 'ES',
  }),
});

const speech = await agent.pay({
  url: `https://mpp.t2000.ai/elevenlabs/v1/text-to-speech/${voiceId}`,
  method: 'POST',
  body: JSON.stringify({
    text: (translated.body as { translations: { text: string }[] }).translations[0].text,
    model_id: 'eleven_multilingual_v2',
  }),
});

// The gateway re-hosts the audio on its artifact store — speech.body.url is durable.
console.log((speech.body as { url: string }).url);

Expected output

3 calls · ~$0.14 · ~12s · 0 taps
A Spanish-voiced .mp3 of the original clip, on a durable URL

​
Extend it

  • Target any of DeepL’s 30+ languages by changing target_lang (FR, DE, JA, …)
  • Swap DeepL for Google Translate (/translate/v1/translate) for 130+ languages
  • Generate captions too: feed the transcript to Claude (/anthropic/v1/messages) for an SRT
  • Loop over several target_lang values in parallel to ship one clip in five languages
