LumaEcho is a voice-first social platform for language learners. Users post short audio messages and respond with "echoes" — voice replies. Every post is automatically transcribed and translated, so speakers of different languages can understand each other instantly.

You record a voice message of up to 60 seconds directly in your browser — no app download required. The audio is automatically transcribed using AI (OpenAI Whisper) and translated into other languages via DeepL.

LumaEcho supports transcription and translation for dozens of languages including English, German, French, Spanish, Italian, Dutch, Polish, Portuguese, Japanese, Chinese, Korean, Arabic, and many more. The interface is available in 8 languages.

Yes, LumaEcho is completely free to use. You can create an account, post voice messages, reply with echoes, and use translation features at no cost.

An echo is a voice reply to a post. Just like sound echoes back, your voice response echoes back to the original poster. Echoes can themselves receive replies, creating threaded voice conversations.
