YouTube 与 B 站逐句精听、跟读节奏控制与学习资产同步。 Shadow Language turns YouTube and Bilibili videos into sentence-by-sentence English listening and shadowing practice. - Show English captions with previous, next, replay, play/pause, sentence loop, and speed controls. - Hover captions to pause at the end of the current sentence and practice speaking along. - Look up words and save words, phrases, and sentence patterns. - Manage learning assets, video progress, vocabulary settings, and local review cards. - Sign in to sync progress and saved learning assets across devices, with export and account deletion controls. - The public corpus shows curated video metadata and learning metrics; it does not upload captions from ordinary watch pages. Player practice and local saving work without sign-in. The extension does not record audio, read cookies or full browsing history, or access Google passwords.
