Researchers and developers in AI-driven animation looking for a tool to generate emotion‑aligned, multi-character audio‑driven avatar videos
About HunyuanVideo-Avatar
HunyuanVideo‑Avatar supports animating any input avatar images to high‑dynamic, emotion‑controllable videos using simple audio conditions. It is a multimodal diffusion transformer (MM‑DiT)‑based model capable of generating dynamic, emotion‑controllable, multi‑character dialogue videos. It accepts multi‑style avatar inputs, photorealistic, cartoon, 3D‑rendered, anthropomorphic, at arbitrary scales from portrait to full body. Provides a character image injection module that ensures strong character consistency while enabling dynamic motion; an Audio Emotion Module (AEM) that extracts emotional cues from a reference image to enable fine‑grained emotion control over generated video; and a Face‑Aware Audio Adapter (FAA) that isolates audio influence to specific face regions via latent‑level masking, supporting independent audio‑driven animation in multi‑character scenarios.

AvatarFX
Character.AI has unveiled AvatarFX, an AI-powered video generation tool currently in closed beta. This technology enables users to animate static images into realistic, long-form videos featuring synchronized lip movements, gestures, and expressions. AvatarFX supports a variety of visual styles, including 2D animated characters, 3D cartoon figures, and non-human faces like pets. It maintains high temporal consistency in facial, hand, and body movements, even in extended videos, ensuring smooth and natural animations. Unlike traditional text-to-image generation methods, AvatarFX allows users to create videos directly from existing images, offering greater control over the final output. AvatarFX is particularly beneficial for enhancing AI chatbot interactions, enabling the creation of lifelike avatars that can speak, emote, and engage in dynamic conversations. Users interested in early access can apply through Character.AI's platform.

Percify
Percify uses cutting-edge AI to generate the most realistic avatars from just a single image. Its advanced technology creates photorealistic faces, perfect lip-synchronization, and natural expressions. The platform features AI avatar generation, voice cloning (best-in-class voice replication), lip-sync technology, pre-built realistic avatar templates, and avatar animation tools. You upload a clear image of a face, supply an audio clip or write a prompt, and with a few clicks, you generate a talking avatar video, complete with matching facial expressions and syncing. The system emphasizes precision lip-syncing, emotional expression, voice cloning, identity preservation (consistent facial features throughout the video), and neural-powered processing to enable natural human-like movements. The UI guides users in four steps: upload image, upload audio, write a prompt, and then generate the video.
