RecEcho: YouTube Shadowing Master

About

Turn YouTube into Your Personal English Speaking Coach.

RecEcho is the ultimate tool for practicing the Shadowing Technique—the most effective method for improving pronunciation and fluency. Stop manually pausing videos; let RecEcho handle the rhythm while you focus on speaking.

Why Install RecEcho? Most learners struggle to keep up with native speakers. RecEcho automatically detects sentence boundaries in YouTube captions, pausing the video after every sentence to give you time to repeat (shadow) what you heard. It records your voice, letting you compare it instantly with the original audio.

🌟 Key Features:

🎙️ Smart Auto-Pause: Automatically pauses video at the end of every sentence (detects punctuation like . ? ! ").
🎧 Instant Recording: Records your voice during the pause and auto-replays the original audio for comparison.
💾 MP3 Export: Save your practice sessions as high-quality, small-size MP3 files to track your progress.
📚 Offline Dictionary: Click any word in the subtitles for an instant definition. Powered by a local Oxford-grade dictionary (IndexedDB)—zero latency, zero tracking.
📝 Vocabulary Log: Automatically saves words you look up. Export them to Markdown (
.md
) for your notes.
🎮 Gamified Learning: Earn "Stars" for every sentence you practice. Unlock themes (Cyberpunk, Dark Mode) in the Shop to stay motivated.
🔒 Privacy First & Offline Capable RecEcho is built for privacy.
