In the current beta version (3.33beta) there is support for live transcription of the current call. You need to install Whisper via "Options / AI Chat / Transcription" or at CLI prompt via "stt install".
If you have a call you can open the context menu in call list and start a transcription. A new window should appear and show the detected words.
Keep in mind that you need a powerful PC with a good GPU tu use that.

Comments are welcome.
