ESC4U

ESC4U is an invitation-only English learning app. Accounts are provisioned by the ESC4U team; there is no public sign-up and nothing is sold in the app. What you can do: • Watch lesson videos with sentence-by-sentence cards, bilingual subtitles, sentence repeat and speed control. • Intensive listening for audio lessons: one sentence at a time, loop, blind-listening mode. • Read full transcripts with Chinese translation; tap any word to see its meaning and add it to your word list. • Shadow reading with on-device speech recognition: read a sentence aloud and see which words you missed. Recordings stay on your device. The app interface is in Simplified Chinese. Learning materials available to the demo account are public-domain content from VOA Learning English.
