SentenceDeck

SentenceDeck turns any text into reusable audio flashcards, one sentence at a time. Paste an article, story, or study material, and the app automatically segments it into natural sentences, generates high-quality audio for each one, and guides you through a structured listen-record-compare practice flow. HOW IT WORKS 1. Paste or type any text into the Editor 2. The app splits it into sentences using intelligent segmentation 3. Audio is generated for every sentence — once generated, cached forever 4. Practice each sentence: hear the reference, record yourself, play back and compare PRACTICE FLOW The heart of SentenceDeck is its A/B practice loop. For each sentence you: - Listen to the reference audio - Record your own attempt - Play back your recording to self-evaluate - Optionally hear the reference again for side-by-side comparison Smart silence detection automatically ends your recording when you stop speaking — no button tapping needed. The detection adapts to background noise and adjusts timeouts based on sentence length. TWO TTS ENGINES System Voices — Built into iOS. Free, works offline, zero setup. Great for everyday practice.
