Overview

Product summary

Review the store description, core capabilities, and common use cases.

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.

nhược điểm: chỉ chọn được 1 giọng đọc tiếng việt . Không tự động chỉnh được tốc độ giọng đọc. Thỉnh thoảng đọc sub bị chậm ( dù đã đặt tốc độ 2.0). Nếu giảm tốc độ video xuống 0.8x, sẽ gây ra méo mó âm thanh. ưu điểm: giá rẻ Rất cần tính năng làm giảm tốc độ video theo tốc độ đọc phụ đề bị chậm.

It will not work well on Linux because the instructions to get more voices are the ones that are installed on Microsoft/Mac (that each company has created themselves).Not sure what is meant by requiring one official subtitle / caption,if auto generated subtitles or what but it should have said it's not Linux compatible in description or requires a complex work-around.
