Speech to Video
Generate video driven by speech audio input using Wan 2.2.
Overview
The Speech to Video node creates video content driven by speech audio. It uses Wan 2.2 to generate visual content that corresponds to the spoken input, offering fine-grained control over generation parameters.

Best Practices
- Use clear, well-recorded speech audio for best results
- Provide a descriptive prompt alongside the audio for better visual control
- Start with default advanced settings and adjust only if needed
- Higher inference steps improve quality but increase generation time
Common Use Cases
- Create video presentations driven by narration
- Generate animated content from podcast audio
- Build speech-synchronized visual content
- Create talking character animations from audio
Tips
- 480p (3cr) is great for quick previews; 580p (5cr) is a middle option; use 720p (6cr) for final output
- Increase inference steps for more detailed results at the cost of longer processing
- The Guidance Scale controls how closely the output follows your prompt — higher values are more faithful but less creative
