Show HN: Whistle Translator

An app for Mac and Windows that turns your voice into text and translates it, entirely on your computer. Speak in seven languages, translate into eight, record whole meetings, and hold a shortcut in any app to dictate. Nothing you say ever leaves your computer.

Version 0.4.0 · Free · Mac: Apple Silicon, macOS 12 or later, 6.0 MB · Windows: 10 or 11, x64, 5.6 MB

Or with Homebrew: brew install --cask msdocs/tap/whistle-translator

Turn off the kitchen lights and set a timer for ten minutes.

Schalten Sie die Küchenbeleuchtung aus und stellen Sie einen Timer für zehn Minuten ein.

Speech recognition and translation both run on your computer's processor. After a one-time model download, it works on a plane, in a basement, or with Wi-Fi switched off.

Hold ⌥ Space (Alt+Space on Windows) in Mail, Slack or a browser, speak, release, and your words are typed at the cursor.

Hold ⌥ ⇧ Space (Alt+Shift+Space) to speak in one language and type in another. A floating pill shows your words as you speak.

See the transcript appear as you talk. Each sentence is translated the moment you finish it.

No account, no cloud, no telemetry. Your audio and text are processed locally and never uploaded.

Play any translation aloud with your system's built-in voice for that language.

Meeting mode transcribes for as long as you talk, saves a timestamped transcript and its translation as it goes, and keeps your computer awake until you stop.

Open a WAV file of any length and get its transcript and translation.

The app isn't signed by Apple or Microsoft yet, so your computer asks you to confirm it the first time.

The app grew out of a small Python project: offline speech-to-text and translation in a few lines, from a WAV file, the microphone or a live stream.
