To edit a speaker's name in transcripts, you can click on the speaker's label (such as "Speaker 1", "Speaker 2", etc.) which will allow you to change their name or alias. Once you make the change, you may be prompted to decide whether you want to apply this change to just one instance or throughout the entire transcript where that speaker has been identified.
Furthermore, if there is a need to update a speaker's profile with more details, such as company affiliation or role, please click "Edit participant" and add new speaker from the popup. Then, you can go back to the interview and click the speaker's label again to choose the participant's name from the dropdown list.
If multiple speakers are not detected or grouped together, you may want to regenerate transcript by clicking the button "Regenerate transcript" under the video.
