Deep Shadow: English Shadowing

Practice English rhythm and intonation with focused listen, speak, and compare drills on captioned YouTube™ videos.

Turn the English videos you already watch into focused speaking practice. Deep Shadow breaks captioned video into natural phrases. For each phrase, it plays the original, cues you to repeat it, records your voice, then plays the original and your take back to back. Hear the difference, repeat until the rhythm feels right, then move on. WHAT YOU CAN DO • Practice with captioned English videos on YouTube™ • Train rhythm, stress, linking, and intonation • Slow each phrase from 1× to 0.5×, then finish at natural speed • Repeat with Space and advance with Right Arrow • Hide the video in Focus mode and train by ear • Switch to Watch mode and resume normal playback anytime PRIVATE BY DESIGN Your microphone is used only while you repeat a phrase. Recordings stay in memory on your device, are played back for comparison, and are then discarded. Deep Shadow has no accounts, analytics, ads, cloud uploads, or saved voice history. WHAT YOU NEED • Desktop Chrome 114 or later • A YouTube™ video with English subtitles or closed captions • A microphone; headphones are recommended Deep Shadow is built for intermediate and advanced English learners who understand the words and want their speech to sound more natural.
