How to get live transcription and speaker with Meeting SDK

I want to get Live Transcription and who spoken in real time on Japanese with Meeting SDK for Windows(C++) .
Looking at this reference, it says that it can be obtained by ltMsg and speaker_id respectively, but no matter what account you speak with, only the same value is entered for speaker_id (speaker_id is 2 anytime and anyone).


  1. Is speaker_id working?
  2. Are there other ways to identify the speaker of the transcription?

Which Windows Meeting SDK version?
Meeting SDK for Windows(C++) v.5.12.8

Get and show LiveTranscription with speakerID on my app with this code.

void MeetingInfoDialog::onLiveTranscriptionMsgReceived(const wchar_t* ltMsg, unsigned int speaker_id, ZOOM_SDK_NAMESPACE::SDKLiveTranscriptionOperationType type)
	switch (type)
	case ZOOM_SDK_NAMESPACE::SDK_LiveTranscription_OperationType_Complete:
		CString msg = L"";
		msg.AppendFormat(L"WHO:%d LT:%s\r\n", speaker_id, ltMsg);

And result…

Device (please complete the following information):

  • OS: Windows 10 Pro
