About
Synthesia’s AI Video Translator is a web-based video dubbing tool focused on translating spoken videos into other languages. The page shown here is specifically for Spanish to English translation, but it also lists many other supported languages and dialects.
This is useful when you want faster localization with a more natural result than basic subtitles alone. According to Synthesia, it can preserve the original voice, sync lip movements, support multiple speakers, and auto-generate subtitles for the dubbed video.
Responds to prompts but takes no autonomous action.
