Show DEV: EchoPod — Learn Languages with Real Podcasts, AI Transcripts & Translations

Описание и применение

EchoPod — бесплатное приложение на Flutter, которое превращает реальные подкасты в уроки языка с точными транскрипциями, мгновенным переводом слов и офлайн‑режимом.

Задача

Learners need immersive language lessons from real podcasts but existing tools lack accurate transcripts, audio sync, or free translation features.

Результат

EchoPod delivers free, accurate, word‑level transcripts with audio sync, instant translation for 150+ languages, and offline learning, addressing gaps in existing language‑learning tools.

• 2. User selects a podcast episode to learn.
• 3. EchoPod fetches the episode and generates a word‑level transcript via Groq Whisper large‑v3‑turbo.
• 4. Transcript is stored locally with Drift SQLite and synced with Supabase backend.
• 5. User taps any word or phrase to instantly translate it into one of 150+ languages.
