Multitalk

Generate realistic talking videos from a single photo with MultiTalk — MeiGen-AI's revolutionary audio-driven conversational video framework. Unlike traditional talking head methods that only animate facial movements, MultiTalk creates lifelike videos with perfect lip synchronization, natural expressions, and dynamic body language.

Why It Looks Great

Perfect lip sync: Advanced audio analysis ensures precise mouth movements matching every syllable.
Full-body animation: Goes beyond faces — animates natural body movements and gestures.
Camera dynamics: Built-in Uni3C controlnet enables subtle camera movements for professional results.
Instruction following: Control scene, pose, and behavior through text prompts while maintaining sync.
Multi-person support: Animate conversations with multiple speakers in the same scene.
Extended duration: Generate videos up to 10 minutes long.

How It Works

MultiTalk combines three powerful technologies for optimal results:

Component	Function
Wav2Vec Audio Encoder	Analyzes speech nuances including rhythm, tone, and pronunciation patterns
Wan2.1 Video Diffusion	Understands human anatomy, facial expressions, and body movements
Uni3C Controlnet	Enables dynamic camera movements and professional scene control

Through sophisticated attention mechanisms, MultiTalk perfectly aligns lip movements with audio while maintaining natural facial expressions and body language.

Parameters

Parameter	Required	Description
image	Yes	Portrait image of the person to animate (upload or public URL).
audio	Yes	Audio file for lip synchronization (upload or public URL).

How to Use

Upload your image — a clear portrait photo works best.
Upload your audio — speech, singing, or any vocal audio.
Run — click the button to generate.
Download — preview and save your talking video.

Pricing

Per 5-second billing based on audio duration.

Duration	Cost
5 seconds	$0.15
30 seconds	$0.90
1 minute	$1.80
5 minutes	$9.00
10 minutes (max)	$18.00

Best Use Cases

Virtual Presenters — Create AI spokespeople for videos and training content.
Content Localization — Dub content into different languages with matching lip movements.
Music Videos — Generate singing performances from static photos.
E-learning — Produce instructor-led courses without filming.
Social Media — Create engaging talking-head content at scale.
Multi-person Conversations — Animate group discussions and dialogues.

Pro Tips for Best Results

Use clear, front-facing portrait photos with good lighting.
Ensure faces are clearly visible without obstructions.
High-quality audio with minimal background noise produces better sync.
Neutral or slightly open mouth expressions in source images work best.
For conversations, provide distinct audio tracks for each speaker.
Test with shorter clips before generating longer videos.

Notes

Maximum supported video length is 10 minutes.
If using URLs, ensure they are publicly accessible.
Processing time scales with audio duration.
Best results come from portrait-style images with clear facial features.

Multitalk API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/wavespeed-ai/multitalk 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 Multitalk below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/wavespeed-ai/multitalk" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "image": "https://example.com/your-input.jpg",
    "audio": "https://example.com/your-audio.mp3",
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "seed": -1
}'

# 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("wavespeed-ai/multitalk", {
        "image": "https://example.com/your-input.jpg",
        "audio": "https://example.com/your-audio.mp3",
        "prompt": "A cinematic shot of a city at sunset, soft golden light",
        "seed": -1
});

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

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "wavespeed-ai/multitalk",
    {
    "image": "https://example.com/your-input.jpg",
    "audio": "https://example.com/your-audio.mp3",
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "seed": -1
}
)

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

Multitalk API — Frequently asked questions

What is the Multitalk API?

Multitalk is a WaveSpeedAI model for video generation from images, exposed as a REST API on WaveSpeedAI. MultiTalk converts one image and audio into audio-driven talking/singing videos (Image-to-Video), supporting up to 10 minutes. 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 Multitalk 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/wavespeed-ai/multitalk.

How much does Multitalk cost per run?

Multitalk starts at $0.15 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 Multitalk accept?

Key inputs: `prompt`, `image`, `audio`, `seed`. 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/wavespeed-ai/multitalk.

How long does Multitalk take to generate?

Average end-to-end generation time on WaveSpeedAI is around 152 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Multitalk outputs commercially?

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