Introducing Wan 2.2 Speech-to-Video: Transform Images and Audio Into Cinematic Videos

The future of digital content creation has arrived. WaveSpeedAI is excited to announce the availability of Wan 2.2 Speech-to-Video (S2V), a groundbreaking AI model that transforms static images and audio into high-fidelity videos with remarkably realistic facial expressions, body movements, and professional camera work. Whether you’re creating digital avatars, producing training videos, or building engaging marketing content, Wan 2.2 S2V delivers film-quality results at a fraction of traditional production costs.

What is Wan 2.2 Speech-to-Video?

Wan 2.2 S2V represents a major advancement in audio-driven video generation. Built on Alibaba’s robust Wan2.2 video diffusion model, this specialized variant is designed specifically to tackle one of AI’s most challenging problems: creating natural, synchronized character animations that meet film and television production standards.

Unlike simpler lip-sync tools that merely animate mouth movements, Wan 2.2 S2V generates complete, coherent videos with nuanced character interactions, realistic body language, and dynamic camera work. The model understands both the audio signals and visual information, producing results that look genuinely cinematic rather than artificially generated.

The model supports both full-body and half-body character generation, making it versatile enough for everything from corporate talking-head videos to full-scene character performances.

Key Features and Capabilities

Superior Audio-Visual Synchronization

Wan 2.2 S2V employs a powerful Wav2Vec audio encoder to understand the nuances of speech—including rhythm, tone, and pronunciation patterns. Through sophisticated attention mechanisms, it achieves perfect alignment between lip movements and audio while maintaining natural facial expressions throughout.

Benchmark-Leading Performance

In extensive testing against competing models like Hunyuan-Avatar and OmniHuman, Wan 2.2 S2V consistently outperforms in critical metrics:

• FID (Video Quality): Produces cleaner, more realistic frames
• EFID (Expression Authenticity): Generates more believable facial expressions
• CSIM (Identity Consistency): Maintains character appearance throughout the video

Where Hunyuan-Avatar struggles with facial distortion during large movements, and OmniHuman produces limited motion amplitude, Wan 2.2 S2V excels at generating diverse, dynamic motion while maintaining identity consistency.

Instruction Following

Unlike simpler generation methods, Wan 2.2 S2V can follow text prompts to control the scene, pose, and overall behavior while maintaining audio synchronization. This gives creators unprecedented control over the final output.

Extended Video Length Support

Generate videos up to 10 minutes in length—far exceeding the capabilities of most competing platforms. This makes it ideal for training videos, presentations, and long-form content without the need for complex stitching or editing.

Flexible Resolution Options

• 480p output at $0.15 per 5 seconds
• 720p output at $0.30 per 5 seconds

Real-World Use Cases
