SentenceDeck – Learn languages with real sentences, not word lists

Summary: SentenceDeck converts any text into sentence-by-sentence audio flashcards for language learning. It auto-splits text, generates TTS audio using offline or cloud voices, and enables practice through a listen-record-compare shadowing loop with smart silence detection and local audio caching.

What it does

It transforms pasted text into natural sentences, creates reference audio with TTS, and supports practice by recording and comparing user speech with the original audio.

Who it's for

Language learners seeking sentence-based practice to improve natural speaking skills.

Why it matters

It addresses the limitations of word lists by focusing on sentence-level practice for more natural language acquisition.
