SentenceDeck: Shadowing

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. Only a SentenceDeck ZIP can import compatible articles and audio on a new device; practice progress is not restored. Exported merged audio is for listening only and cannot be imported
• Clearer pricing: each sentence is generated as you practice. The same sentence is charged once and cached for replay with the same premium voice and style settings; changing the premium voice or style may generate it again and use characters again

TWO VOICES — ONE IS FREE
System voice: built into iOS. Free, offline, unlimited.
Premium voice: natural, expressive male and female voices with several speaking styles. Pay only for the sentences you practice; nothing expires.
