VoiceGlyph - English Listening Cards for YouTube™

VoiceGlyph is an English-listening study tool that keeps your YouTube learning from going in one ear and out the other. The moment you think "wait, what did they just say?" — click once. That sentence becomes a review flashcard with the subtitle text, a translation, and AI listening tips. The short audio snippet attached to each card (a few seconds, 10s max) is stored in your own Google Drive, and is not stored on our servers. ■ Features - Turn the sentence you couldn't catch into a flashcard in one click (subtitle text + short audio snippet + scene image) - AI translation and listening tips explaining why the phrase was hard to catch - Spaced-repetition review (SRS) in the companion web app (voiceglyph.com) - Shadowing practice: repeat after the model voice and compare; AI scores each word (speech recognition runs on your device) - Radio mode: hands-free review of your cards (original → slow → translation) - Study stats, streaks, and achievement badges ■ Available in 11 languages The extension, the web app, and the AI explanations are all available in English, Japanese, Korean, Traditional Chinese, Simplified Chinese, Spanish, Portuguese, French, German, Italian, and Arabic. Choose your language once and everything follows — including the explanations written for you. ■ Privacy-first design - Card audio, images, subtitles, translations, and explanation text are stored in the "VoiceGlyph" folder of your own Google Drive.
