Product summary

SimIntpr is a virtual Simultaneous Interpreter for YouTube videos. It translates YouTube video subtitles and speaks them out.

If you want to watch any YouTube video and hear the voice of your own language, SimIntpr is your thumb of choice. It can translate the YouTube subtitles / captions into almost all widely used languages and read them out.

SimIntpr uses state-of-art Text-To-Speech(TTS) Engine to generate synthesized voice. It supports as many as 67 voices covering almost 30 different languages.

Currently, to make the extension work, the YouTube video should have at least 1 official subtitle. You need to choose a YouTube official subtitle as the translation source, then select your preferred voice language, tune, speed, etc.

We're working on supporting uploading your local subtitles, or links to external subtitles.

Once you set up, SimIntpr speaks out your preferred language and voice, just as a virtual simultaneous interpreter. The translated voice does not conflict with the YouTube original one. So you can keep them both and adjust the volume separately as you wish.
