During automatic subtitle creation, the Video.Taxi engine recognizes the different speakers. These are named S1, S2, S3 etc. by default. If you want to rename them, it's very easy.
Edit the subtitles of the video in the “UTs & transcripts” area.
Next to the subtitles, you will see the different speakers that have been recognized on the right. To change the name, click on the pencil icon to the right of the speaker.
Select the designation or name and click on “Rename speaker”. If you rename a speaker to an existing name, the paragraphs of these speakers will be merged.
The changed name now appears on the left where S2 used to be. Even if you download the subtitles as a transcript, the changed name will appear.
