SentenceDeck vs ShadowTuber

Shadowing, made simple. Paste any text — a news story, a podcast transcript, a page from your textbook — and SentenceDeck turns it into a sentence-by-sentence speaking drill: hear it, say it, hear yourself back. No scripted lessons, no grades. Just the method interpreters and polyglots swear by, applied to the exact text you want to master. HOW A SESSION WORKS For every sentence, SentenceDeck: 1. Plays a clear reference voice 2. Records you automatically — recording stops when you stop speaking 3. Plays your voice back so you can hear the difference Switch on A/B compare to hear reference and recording back to back, lock a tricky sentence to loop it, and change playback speed (0.75× to 1.5×) without regenerating audio. WHAT'S NEW IN 1.5 • A redesigned home screen: pick up where you left off, and see today's sentences, your streak and your lifetime total at a glance • A richer premium voice with selectable voice styles • Free Sample articles so you can try the flow before adding your own text • Backup & Export: premium audio is included in your device backup when backups are enabled and sufficient backup space is available.
