+Call live transcription
+-----------------------
+
+Call live transcription allows to transcribe the speech in real-time during a call. It is set up by the system administration (High-performance backend and `Live Transcription App <https://apps.nextcloud.com/apps/live_transcription>`_ are required).
+Moderators need to set the language of the transcription in the conversation settings. All participants then can enable or disable the transcription for themselves in the call bottom bar.
+When enabled, the transcription will appear in the bottom and will be updated in real-time.
