No, we do not require transcriptionists to do complete and accurate speaker ID. It is helpful if in focus groups you identify the moderator (Moderator:), and then the participants can be labeled as “Respondent:” or any other placeholder you choose so that the format is preserved.
For interviews, we ask you label as “Q:” for the interviewer and “A:” for the respondent. All ID tags should be in italics, and “A:” is also in bold.
However, if you have a multi-speaker file that seems like it will be easy to identify all speakers and you want to do the ID, email your project manager to ask if it’s okay to do so. Some files may not need speaker ID at all, so check with your project manager first. Your PM will also give you an updated pay rate at that time.
