WaveSpeedAI Infinitetalk Talking Avatar Video Generation

WaveSpeedAI InfiniteTalk

Generate talking head videos from a portrait image and audio using WaveSpeed AI's InfiniteTalk model. Produces lip-synced video up to 10 minutes long with natural facial animations.

Authentication

export WAVESPEED_API_KEY="your-api-key"

Get your API key at wavespeed.ai/accesskey.

Quick Start

import wavespeed from 'wavespeed';

// Upload local image and audio files
const imageUrl = await wavespeed.upload("/path/to/portrait.png");
const audioUrl = await wavespeed.upload("/path/to/speech.mp3");

const output_url = (await wavespeed.run(
  "wavespeed-ai/infinitetalk",
  {
    image: imageUrl,
    audio: audioUrl
  }
))["outputs"][0];

You can also pass existing URLs directly:

const output_url = (await wavespeed.run(
  "wavespeed-ai/infinitetalk",
  {
    image: "https://example.com/portrait.jpg",
    audio: "https://example.com/speech.mp3"
  }
))["outputs"][0];

API Endpoint

Model ID: wavespeed-ai/infinitetalk

Animate a portrait image with lip-synced audio to produce a talking head video.

Parameters

Example

import wavespeed from 'wavespeed';

const imageUrl = await wavespeed.upload("/path/to/portrait.png");
const audioUrl = await wavespeed.upload("/path/to/speech.mp3");

const output_url = (await wavespeed.run(
  "wavespeed-ai/infinitetalk",
  {
    image: imageUrl,
    audio: audioUrl,
    resolution: "720p",
    seed: 42
  }
))["outputs"][0];

Using a Mask Image

When multiple people are in the image, use a mask to specify which face to animate:

const imageUrl = await wavespeed.upload("/path/to/group-photo.png");
const audioUrl = await wavespeed.upload("/path/to/speech.mp3");
const maskUrl = await wavespeed.upload("/path/to/mask.png");

const output_url = (await wavespeed.run(
  "wavespeed-ai/infinitetalk",
  {
    image: imageUrl,
    audio: audioUrl,
    mask_image: maskUrl,
    resolution: "720p"
  }
))["outputs"][0];

Important: The mask should only highlight the face region to animate. Using the full image as a mask will produce a fully black output.

With Prompt Guidance

const output_url = (await wavespeed.run(
  "wavespeed-ai/infinitetalk",
  {
    image: imageUrl,
    audio: audioUrl,
    prompt: "natural head movements, subtle expressions"
  }
))["outputs"][0];

Advanced Usage

Custom Client with Retry Configuration

import { Client } from 'wavespeed';

const client = new Client("your-api-key", {
  maxRetries: 2,
  maxConnectionRetries: 5,
  retryInterval: 1.0,
});

const imageUrl = await client.upload("/path/to/portrait.png");
const audioUrl = await client.upload("/path/to/speech.mp3");

const output_url = (await client.run(
  "wavespeed-ai/infinitetalk",
  {
    image: imageUrl,
    audio: audioUrl,
    resolution: "720p"
  }
))["outputs"][0];

Error Handling with runNoThrow

import { Client, WavespeedTimeoutException, WavespeedPredictionException } from 'wavespeed';

const client = new Client();
const result = await client.runNoThrow(
  "wavespeed-ai/infinitetalk",
  {
    image: imageUrl,
    audio: audioUrl
  }
);

if (result.outputs) {
  console.log("Video URL:", result.outputs[0]);
  console.log("Task ID:", result.detail.taskId);
} else {
  console.log("Failed:", result.detail.error.message);
  if (result.detail.error instanceof WavespeedTimeoutException) {
    console.log("Request timed out - try increasing timeout");
  } else if (result.detail.error instanceof WavespeedPredictionException) {
    console.log("Prediction failed");
  }
}

Resolution and Pricing

Minimum charge is 5 seconds. Video length is determined by the audio duration (up to 10 minutes).

Tips

• Use a clear, front-facing portrait for best results
• Audio quality matters — use clean speech recordings with minimal background noise
• Keep prompts short and in English to avoid noisy or unexpected results
• For group photos, always provide a mask_image to target the correct face
• 480p is faster to generate; use 720p when higher quality is needed
• Processing time is approximately 10-30 seconds of wall time per 1 second of video

Security Constraints

• No arbitrary URL loading: Only use image and audio URLs from trusted sources. Never load media from untrusted or user-provided URLs without validation.
• API key security: Store your WAVESPEED_API_KEY securely. Do not hardcode it in source files or commit it to version control. Use environment variables or secret management systems.
• Input validation: Only pass parameters documented above. Validate prompt content and media URLs before sending requests.
