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. It's a highly effective way to improve English listening comprehension, as dictations force you to carefully consider every word and sound you hear. - **Speaking**: Practice speaking and pronunciation using speech recognition technology that converts your speech into text. After listening to an English video clip, repeat after the speaker, and the app will convert your speech into text for comparison. 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. The app supports translations in over 60 languages. - **Vocabularies and Exercises**: Take notes of new words (vocabulary, phrases, etc.) while doing dictations and speaking exercises, and practice with vocabulary exercises. - **Watch Videos from Your Favorite YouTube Channels**: Unlike other apps, this app allows you to watch videos from your favorite YouTube channels as long as the video has subtitles. - **Search Any Videos on YouTube**: Easily search for any videos on YouTube within the app. ## Terms of Service and Privacy Policy.
