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.

AB Loop Repeat for Language Learners [Universal Purchase] Buy once, enjoy across iPhone, iPad, and Mac. Cassette Tape is a media player built for one purpose: loop any section of audio or video with a single tap. Whether you are practicing English, Japanese, Chinese, or any other language, just set your A and B points and repeat that section as many times as you need. - AB Loop Repeat — Core Feature • A/B Point Setting Tap once to mark the start (A) of a section, tap again to mark the end (B). The player instantly loops that exact segment — a single sentence, a tricky phrase, or a short expression. Works with both audio and video files. • Repeat Count Control Set a specific number of loops or repeat infinitely. Once the count is reached, playback continues automatically from where you left off, keeping your session flowing. • Fine-Tune Adjustment Nudge the start and end points in 0.1-second increments using the fine-tune slider. Get the loop exactly right without having to re-record or edit your file. • Multiple Saved Segments Save as many loop sections as you need within a single file. Switch between them instantly to move between practice points during a study session. Keep yesterday's focus point and today's side by side. - Media Playback Plays MP3 and WAV audio files as well as MP4 video files. Adjust playback speed from 0.5x to 2.0x — slow down to catch every word, then gradually bring it up to full speed as your comprehension improves. Background playback keeps the audio running even when you lock your screen, with full controls available on the lock screen. Your last playback position is saved automatically so you can pick up exactly where you left off. - AI Subtitle Generation The built-in AI listens to your audio or video and automatically generates subtitles. Everything runs on your device without an internet connection, so your private study files stay private. Use the subtitles to follow along during listening, compare what you hear with what you read during dictation practice, or guide your listen-and-repeat sessions. - Bookmarks and Study Log Whenever you come across an important phrase, a difficult sentence, or a moment worth revisiting, tap the bookmark button to save that exact position instantly. You can attach a note to every bookmark — for example, "review this pronunciation," "key expression," or "needs more listen-and-repeat practice." All bookmarks are listed in one place and a single tap takes you straight back to that moment. As bookmarks accumulate across files, they naturally become a personalized study log that grows with you. - Additional Study Tools • Recent Files — quick access to your regular study materials • Playlist — group files and play them in sequence • Dark mode / Light mode - App Interface Languages Korean / English / Japanese / Simplified Chinese Loop it. Learn it. Level up.
