Recently, an AI digital human platform called HeyGen has suddenly gained immense popularity for its ability to create realistic multilingual video translations. This platform applies advanced artificial intelligence technology to content generation, allowing users to upload video images, select languages, and generate high-quality customized content, including digital human creation and voice conversion functionalities. This significantly lowers the barriers to video production, gaining the favor of numerous creators. HeyGen was founded by former senior engineers from Snapchat and has received support from renowned investment institutions such as IDG and ZhenFund, being regarded as a dark horse in the AI content production field. With the rise of similar tools, a surge in videos featuring virtual characters speaking different languages is expected, which will also raise more concerns about AI ethics and security.
