This tool listens to someone speaking Chinese and, in real time, translates and speaks the English version into a virtual audio channel so that other participants in an online meeting hear English instead. It runs as a Mac application and uses Google's Gemini Live API to handle both the speech recognition and the translation in one step. The setup requires a Mac with a free audio routing tool called BlackHole 2ch installed. This creates a virtual microphone on your system that other apps can use as an audio source. Once you open the Live Interpreter app, you enter a Gemini API key from Google, select your real microphone as the input device, and select BlackHole 2ch as the output device. Then in your meeting software, whether that is Zoom, Google Meet, or another platform, you switch the microphone to BlackHole 2ch. From that point, whatever you say in Chinese is captured, translated, and played back as English speech through the virtual channel so other participants hear only the English voice. The distribution is a ready-to-run Mac app available as a ZIP download from the GitHub releases page, so no Python environment or command-line setup is needed for most users. BlackHole 2ch can be installed with a single command using the Homebrew package manager. If macOS blocks the app from opening because it came from an unrecognized developer, right-clicking the app and choosing Open bypasses that warning. The README is brief and covers only macOS. The tool is specific to that platform because the app format and the BlackHole driver are Mac-only. A Gemini API key from Google is required, and usage costs will depend on how much translation you do through the API.
