Translate YouTube subtitles with bilingual captions, no-caption speech-to-text, and AI dubbing/read-aloud voice.
LingTube helps you translate YouTube subtitles, show bilingual captions, and read the translation aloud while the original video audio keeps playing. Even when a video has no captions, it can automatically process the audio and continue with generated subtitles. It is built for language learning, shadowing, listening practice, commuting, and hands-free watching.

- At first, I thought it could only translate subtitles, but it can also play the translated subtitles aloud! That's amazing :)

- I highly recommend this. Watching videos with other voice recordings was really convenient before, but this one is even more convenient
- Kraska Hodgkiss
- Thanks to the author! Even though I can't use AI translation because I don't have an OpenAI-compatible interface, the free Google Translate is pretty good too.
- Edi Allen
- This is awesome! Not only is it free, but it also supports custom OpenAI API integration for AI translation, and you can even customize the translation scenarios :)
- Tom Holland
