When coding for speakers, what should the code be based on?

The correct approach to coding for speakers involves using the speaker's last name. This practice is rooted in the need for clarity and consistency in documentation. Utilizing the last name helps to ensure that there is no confusion, especially in instances where multiple speakers may have the same first name. It also aligns with common standards in documentation and reporting, where individuals are typically identified by their surname.

Choosing the last name provides a more formal identification of speakers and maintains a level of professionalism, which is particularly important in legal and formal contexts. This method allows for a straightforward way to reference speakers in notes, transcripts, and other recording formats.

While other factors such as the speaker's first name, title, or role in the meeting may provide context, they do not provide the uniformity necessary for efficient record-keeping when multiple individuals are involved. Focusing on the last name supports an organized and efficient coding system that is easily understood and referenced later on.
