Dubbing | AI Video Dubbing API

ElevenLabs Dubbing

ElevenLabs Dubbing automatically translates and dubs video or audio content into different languages. Upload your content, select target language — the model transcribes, translates, and generates natural-sounding speech in the target language while preserving the original voice characteristics and timing.

REST inference API, best performance, no cold starts, affordable pricing.

Why Choose This?

Automatic translation and dubbing End-to-end pipeline: transcription → translation → voice synthesis in one step.
Voice preservation Maintains the original speaker's voice characteristics in the dubbed output.
Multi-language support Supports English, Spanish, French, German, Italian, Portuguese, Chinese, Japanese, Korean, and more.
Auto language detection Automatically detects the source language, or manually specify for better accuracy.
Video and audio support Works with both video files and audio-only content.

Best Use Cases

Content Localization — Translate videos and podcasts for international audiences.
Marketing — Dub promotional content into multiple languages.
Education — Make educational content accessible in different languages.
Social Media — Reach global audiences with multilingual video content.
Corporate Communications — Translate internal videos and training materials.

Pro Tips

Use clean, high-quality source audio for best dubbing results.
Specify source language manually if auto-detection is inaccurate.
Shorter clips process faster — split long content for parallel processing.
Content with clear speech and minimal background noise produces better results.

Notes

Either video or audio is required — upload one of them.
If both video and audio are provided, the model will process video only.
For longer content, split into segments and process separately.

Dubbing API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/elevenlabs/dubbing with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Dubbing below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/elevenlabs/dubbing" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "video": "https://example.com/your-input.mp4",
    "audio": "https://example.com/your-audio.mp3",
    "source_lang": "Auto"
}'

# Response includes a prediction id. Poll for the result:
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# When status is "completed", read the output from data.outputs[0].

Node.js example

// npm install wavespeed
const WaveSpeed = require('wavespeed');

const client = new WaveSpeed(); // reads WAVESPEED_API_KEY from env

const result = await client.run("elevenlabs/dubbing", {
        "video": "https://example.com/your-input.mp4",
        "audio": "https://example.com/your-audio.mp3",
        "source_lang": "Auto"
});

console.log(result.outputs[0]); // → URL of the generated output

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "elevenlabs/dubbing",
    {
    "video": "https://example.com/your-input.mp4",
    "audio": "https://example.com/your-audio.mp3",
    "source_lang": "Auto"
}
)

print(output["outputs"][0])  # → URL of the generated output

Dubbing API — Frequently asked questions

What is the Dubbing API?

Dubbing is a ElevenLabs model for AI inference, exposed as a REST API on WaveSpeedAI. ElevenLabs Dubbing automatically translates and dubs video/audio content into different languages while preserving the original speakers' voices. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Dubbing API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/elevenlabs/elevenlabs-dubbing.

How much does Dubbing cost per run?

Dubbing starts at $0.80 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Dubbing accept?

Key inputs: `video`, `audio`, `source_lang`, `target_lang`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/elevenlabs/elevenlabs-dubbing.

How long does Dubbing take to generate?

Average end-to-end generation time on WaveSpeedAI is around 513 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Dubbing outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (ElevenLabs). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
