What is it?

This project is an online study player for the four volumes of New Concept English. Users can listen to lessons with American-accent audio, click any single sentence to replay it for shadowing practice, and read English and Chinese side by side for each line.

The player is a static site written in HTML, CSS and JavaScript, so it runs in a browser without installation and adapts to phones, tablets and desktops. Lesson content is organized as a resource folder containing a book.json manifest, one MP3 and one LRC lyric file per unit. The LRC format uses timestamps with a pipe character separating English from Chinese text.

Beyond the built-in books, the player can load custom resource folders hosted on any CORS-enabled static server. Each book is registered in a data.json file and opened with a URL hash. The Chinese subtitles were generated with Gemini AI and may contain errors.
