II. Function Introduction

(I) AI Digital Human Functions

Rich Library of Digital Human Avatars: The platform offers over 230 realistic AI digital human avatars, covering various ethnicities, ages, genders, and styles. These avatars can express a wide range of emotions, and their expressions and movements are highly consistent with the spoken content, greatly enhancing the naturalness and appeal of the videos. For example, in an educational video, the digital human Jaz can explain complex knowledge points vividly through expressive facial expressions and gestures.

Personalized Digital Human Creation: Users can create their own personalized digital humans in just 5 minutes. By simply recording their images via a webcam or uploading videos from a smartphone, Synthesia.io can clone the user’s voice, enabling the digital human to speak in 29 languages. For instance, corporate managers can create digital humans resembling themselves for internal company training videos, enhancing employees’ sense of intimacy and identification.

(II) Powerful AI Image Generation Function (Highlight)

Text-Driven Image Generation: When users input detailed text descriptions, Synthesia.io can quickly generate high-quality images that match the descriptions, thanks to its advanced image generation algorithms.

Integration with Digital Humans and Videos: The generated images can be seamlessly integrated into digital human videos, enhancing the visual richness of the videos.
