Overview
What is SimIntpr?
SimIntpr is a virtual Simultaneous Interpreter for YouTube videos. It translates YouTube video subtitles and speaks them out. It translates YouTube subtitles/captions into almost all widely used languages and reads them out using a state-of-the-art Text-To-Speech (TTS) Engine, supporting as many as 67 voices covering almost 30 different languages. To make the extension work, the YouTube video should have at least one official subtitle. The translated voice does not conflict with the YouTube original one.
