什么是 Synthesia?

The platform also includes tools for translating and dubbing existing videos, collaborating on content, and publishing videos for viewers.

Synthesia 能做什么?

AI avatars and voices

Create narrated videos with expressive AI avatars and choose from hundreds of natural-sounding voices. Customizable avatars can use different outfits and backgrounds, while personal avatars can be created from a photo or a recording of yourself.

AI Video Assistant

Turn prompts, scripts, decks, PDFs, websites, and other content into polished videos, giving teams a faster starting point for production.

Translation and dubbing

Translate video content into more than 140 languages, with dubbing that can preserve the speaker’s voice and synchronize mouth movements. Enterprise plans also list one-click translation into more than 80 languages.

Interactive Sessions

Create roleplay scenarios in which avatars respond to learners and push back in difficult conversations, or run conversational surveys that ask questions and collect responses.

Collaboration and brand controls

Use shared workspaces, real-time collaboration, comments, review workflows, brand kits, and branded video pages to keep production organized and on brand.

Programmatic video workflows

Use the Synthesia API to generate videos, translate video libraries, and embed real-time interactive avatars in products. Synthesia also provides an MCP server for creating videos inside Claude or ChatGPT.
