SubVi (Subtitle Video) project helps users learn English effectively with Dictation, Speech recognition, and Quizzes. Videos are sourced from subscribed YouTube channels. ## Features. - **Subtitle**: Watch YouTube videos with their subtitles and side-by-side translations. - **Quiz**: Test your understanding with short quizzes after watching a video (Only support Ted and Ted-Ed). - **Video Summary**: Read a summary of the video if you prefer not to watch it (Only support Ted and Ted-Ed). - **Dictation**: Listen to an English video clip and write down exactly what's being said.

Your speech will be scored based on the Dice coefficient formula. - **Translation**: View side-by-side translations alongside subtitles while doing dictations and speaking exercises.
