What should be avoided when using codes to identify speakers?

Using single initials to identify speakers should be avoided because they can create ambiguity and confusion, especially in situations where there may be multiple individuals with the same initial. When trying to attribute dialogue, especially in a transcript or a recording, clarity is crucial. Single initials do not provide enough context to reliably distinguish between different speakers.

In contrast, full names or combinations of initials and last names can offer clarity, as they usually specify who is speaking without causing confusion. Numbering systems, while they can be impersonal, are often clear enough to differentiate between speakers by assigning a unique identifier to each one. Initials combined with last names can enhance clarity as they uniquely identify a speaker while keeping the reference concise.
