About Infinite Talk AI
Infinite Talk AI is an audio-driven video tool for generating talking avatars with precise lip synchronization. It can convert a single image or an input video plus audio into continuous, identity-preserving videos of unlimited length by synchronizing lips, head movements, body posture, and facial expressions to the audio. The project is released with model weights and code for self-hosting and integrates with Gradio and ComfyUI workflows; it emphasizes stable long-form generation and improved lip accuracy compared to prior methods.

Key Features
Audio-Driven Lip Sync: Converts input audio into highly accurate lip movements, aligning phonemes to mouth motion for realistic speech synchronization.
Sparse-Frame Video Dubbing: Uses a sparse-frame framework to synthesize videos by aligning not only lips but also head movements, body posture, and facial expressions to audio.
Infinite-Length Generation: Supports generation of videos of unlimited duration (longform output) while preserving identity and temporal consistency.
Image-to-Video Mode: Accepts a single image plus audio to create continuous talking-avatar videos, enabling still-to-video conversion for avatars or characters.
Identity Preservation: Maintains consistent facial identity across frames to avoid drift during long or repeated generation.
Open Model & Integration: Model weights, code, and integration examples (Gradio, ComfyUI) are publicly released for self-hosting and customization.
Accurate lip synchronization that aligns mouth movements precisely to input audio
Sparse-frame video dubbing: synchronizes lips, head movements, body posture, and facial expressions rather than only lips
Infinite-length generation: supports unlimited-duration video generation
Image-to-video and video-to-video workflows (single image + audio or input video + new audio)
Open-source model weights and code hosted on GitHub and Hugging Face
Example scripts and entry points provided (e.g., generate_infinitetalk.py, app.py)
Integration examples and UIs: Gradio demos and ComfyUI workflows available
Local inference via Python with models; no official hosted REST API documented
Supports common model toolchain optimizations/workflows (e.g., INT8 quantization mentioned in related repos)
Provides examples, assets, and configuration files in repository (requirements.txt, examples folder)
Use Cases
Multilingual Dubbing: Replace an original audio track with translated speech while preserving the speaker's facial identity and synchronized lip motion for international releases.
Virtual Spokesperson Creation: Generate continuous talking-avatar videos from a single brand image and a script audio file for marketing, tutorials, or product demos.
Content Creator Avatars: Produce long-form talking-avatar videos for streaming, podcasts, or social platforms without filming new footage.
Image-to-Video Social Clips: Turn portraits or character art into short or extended talking clips for social posts, promos, or storytelling.
Automated Lecture or Training Videos: Convert narrated scripts into continuous instructor-facing videos for e-learning and corporate training at scale.
Research and Tooling Integration: Self-host model weights and integrate into custom pipelines (Gradio/ComfyUI) for experimentation, fine-tuning, or production workflows.
Dubbing and localization of video content into other languages with synchronized lip movement
Generating long-form talking-avatar videos from a single image and an audio track
Creating virtual presenters, synthetic spokespersons, and conversational avatars
Film and media post-production for revoicing and synchronized character animation
Research and development for audio-driven video synthesis and face/pose alignment techniques
