Realtime Call Translator

Translates both sides of a video or voice call live — you speak your language, the other person hears theirs, and vice versa.

macOS 14+ Windows & Linux (CI builds) 29 languages MIT

How it works: Mic audio → speech-to-text → translation → TTS → routed back into the call. Local mode uses Whisper + Opus-MT by default; cloud backends optional.

Quick start
