Sentence Echo
Echo YouTube videos sentence by sentence in your language
Hey Product Hunt community! 👋
I’m Seongman, the creator of Sentence Echo.
When learning languages through YouTube, I always found it frustrating to manually pause, rewind, and look up translations sentence by sentence. I wanted a seamless way to practice listening and shadowing without constantly interacting with the screen.
That’s why I built Sentence Echo. It plays YouTube videos sentence by sentence, immediately echoing each line with a translated audio voice so you can absorb both the original audio and its meaning naturally.
Current Stage & Roadmap:
- Where it stands today: To manage initial server and infrastructure costs, anyone can currently listen to our curated library of pre-processed videos (English → Korean, single female voice).
- What’s already built & coming next: The full engine is already developed! Once we secure funding or scale our user base, we plan to open up the core features: letting users paste any YouTube link, translate across multiple language pairs, and choose customized voice models.
I’d love to hear your feedback on the concept, playback flow, or any features you'd like to see next.
Check it out and let me know what you think! 🚀
