For Microsoft Teams meetings
Hear every meeting in your language.
The companion runs next to Teams. It sends the meeting audio for live translation, plays the dubbed voice in English, Hindi or Chinese, and turns Teams down while the dub plays. Subtitles float over your screen.
Choose your computer below.
How it works
- The host installs the app and clicks Start hosting while in the Teams meeting. It captures what Teams plays plus the host's microphone.
- Share the listener link in the Teams chat.
- Everyone picks a language. People with the app hear the dub on their computer with Teams turned down. Anyone can also open the link on a phone with earbuds.
Use headphones. On speakers the dub can leak back into your microphone.

Windows 10 (2004) or 11. On Windows the host captures everything playing on the device Teams uses, so the host should not play the dub on that same device.
Privacy
While hosting, the meeting audio and your microphone are streamed to DubStream for translation. Tell the people in your meeting before you start, as you would for a recording. Listeners only receive audio and text; they send nothing.
