How to translate voice calls on Mac with Translate Chat Voice
Translate Chat Voice turns a Mac into a real-time voice translator for online calls. The app listens through Apple Speech Recognition, translates each direction through the authenticated server, then speaks the translated audio through macOS text-to-speech and the TranslateChatVoice virtual audio devices.
Setup steps
Translate an online call in four steps.
-
01
Open the macOS app
Sign in with Google so the app can connect your plan and usage to the Translate Chat Voice server.
-
02
Choose both languages
Select your language, your partner language, and the available macOS text-to-speech voice preference for each side.
-
03
Route the calling app
Choose TranslateChatVoice Mic as the microphone and TranslateChatVoice Speaker as the speaker or output in the calling app.
-
04
Start translating
Press Start translating. Your speech is translated to your partner, and your partner speech is translated back to your speakers or headphones.
Product details
Built for two-way voice translation on macOS.
Private local transcript
The macOS app can keep a bilingual transcript locally on your Mac and export it as CSV when you need a record.
Conversation context
You can add a short context note during the call so business terms, names, tone, and pronouns stay natural in later translations.
