ViDubbing is a Chrome extension that automatically adds Vietnamese voice-over to YouTube videos, Coursera, Udemy, and Google Drive, allowing you to listen to Vietnamese directly on the page you are viewing without having to download the video. Many lectures, courses, and great videos are only in English. Reading subtitles requires you to constantly look at the text, which makes it hard to focus on the images, slides, or sample actions. With ViDubbing, you just need to listen as if you were watching a pre-dubbed video. Simply press the ViDubbing button on the player or the D key, and the natural Vietnamese voice will read along with the rhythm of the video, while the original audio is quieter in the background. The next sentence is always prepared in advance, so there is no waiting. The speed, volume of the voice, and Vietnamese subtitles can all be adjustable according to your preference.
