Infinite Talk AI Key Features

Precise Lip Sync & Expression Alignment

Advanced audio-driven synchronization that aligns mouth shapes, facial expressions, head turns, and basic body posture to match speech rhythm and intonation for natural-looking talking videos.

Infinite-Length Generation

Generate lip-synced videos with no strict duration limit while preserving identity consistency and animation stability across long-form content like lectures, interviews, and podcasts.

Multi-Input Modes (Audio+Image / Audio+Video)

Create realistic talking portraits from a single image or dub existing footage by uploading a source video and a replacement voice track for seamless dubbing.

Prompt-Controlled Expressions & Motion

Use optional text prompts to guide expressions, gestures, and emotional tone, allowing fine-grained control over the avatar's performance without manual animation.

Resolution & Export Flexibility with High Stability

Export in multiple resolutions (480p/720p/1080p) and enjoy stable, distortion-free animations with reduced artifacts for professional or social outputs.
