Public audio devices
Calling apps should select TranslateChatVoice Mic and TranslateChatVoice Speaker, the two user-facing devices exposed for translated calls.
Virtual microphone translator
Virtual microphone translation on macOS with TranslateChatVoice Mic
Translate Chat Voice uses app-owned virtual audio devices so translated speech can enter a calling app as microphone audio. The public devices are TranslateChatVoice Mic for outgoing translated speech and TranslateChatVoice Speaker for incoming partner audio.
Setup steps
How the virtual audio route works.
-
01
Your microphone is captured
The macOS app listens to your selected physical microphone only after you start translation.
-
02
Speech is translated
Recognized text, language direction, and bounded context are sent to the server for translation.
-
03
Translated speech enters the call
macOS text-to-speech creates audio and sends it to TranslateChatVoice Mic, which the calling app sees as its microphone.
-
04
Partner audio comes back
The calling app sends partner audio to TranslateChatVoice Speaker so the app can translate it back to your selected output device.
Product details
A focused alternative to manual audio plumbing.
Internal endpoints stay hidden
TranslateChatVoice Mic Feed and TranslateChatVoice Speaker Tap are internal endpoints used by the app and should not be selected in calling apps.
Session-aware routing
Physical devices connect when translation starts and are released when translation stops, while virtual devices remain visible while the app is open.
From the macOS app
Confirmed from the app implementation.
- TranslateChatVoice Mic is the virtual microphone that calling apps can select as input.
- TranslateChatVoice Speaker is the virtual speaker or output route that carries partner audio back into the translator.
- The packaged HAL backend exposes the public virtual microphone and speaker devices on macOS.
- The app excludes virtual, aggregate, auto-aggregate, and TranslateChatVoice endpoints from physical device picker choices.
