Lookup dictionary You can immediately look up the dictionary by tap the word. The shadowing technique Shadowing is a language learning technique where you repeat an audio just after you hear it. You’re acting like an “echo” or a “shadow” (hence the name “shadowing"). You listen to the words and then say them back out loud. Shadowing helps you develop all the physical aspects of fluency. These include things like pronunciation, prosody, and rhythm of English. It looks like this: 1. Find a video of your interest 2. Listen to the audio from video first 3. Shadow the audio with a transcript 4. Shadow without a transcript Other Support full screen mode Favorite video Add videos to favorites and watch them later How do I use: Open the app and select the video you want to watch. You can enter keywords to search for videos, note that only videos with closed captions will be displayed. Note: This app only translates from existing subtitles of the video, because not all Youtube videos have subtitles, so some videos cannot be translated.
