Starting the server makes your event live and ready for listeners.

1
Go to Server Settings

Click on Server in the sidebar menu.

Listeners Don't Need an App
Everything works in the web browser. Listeners just scan, pick their language, and listen!

When AI translation is active, listeners can see real-time subtitles in both the original and translated languages.

Subtitles Are Automatic

When AI translation is running, subtitles are generated automatically. No extra setup is required.

2
What Listeners See

Listeners on an AI-translated channel will see:

  • Translated Subtitles - The translated text in their selected language
  • Original Text - The original transcript from the speaker
  • Real-Time Updates - Subtitles appear as the speaker talks, with partial results that refine as more context is captured

Toggle Subtitles

Listeners can toggle subtitles on or off from their player controls. The subtitle overlay appears at the bottom of the audio player with a smooth animated display.

Subtitle Accuracy
Subtitles are powered by AI speech recognition and translation. Accuracy may vary depending on audio quality, background noise, and speaking speed. Clear audio input provides the best results.
