Used for tracks which consist solely of dialogue, and which aren’t credited to anyone on the release tracklist. For example, the “Royale With Cheese” discussion from Pulp Fiction would be correctly assigned to [dialogue], not to “John Travolta & Samuel L. Jackson”, since the tracklist has no artists for that track. Their performances within the track should instead be indicated by a vocals relationship (generally spoken vocals ).
Only tracks are specifically mentioned by this, but the recording could easily be credited to the performers, which are known in the above example. They don’t appear on the back cover’s tracklist but are credited in the booklet of e.g. Pulp Fiction: Music From the Motion Picture.
Currently the above example recording is credited to John Travolta & Samuel L. Jackson (contradiction to the style example?), but the track AC is [dialogue] for almost all of the linked tracks. After I merged two entities of this recording in https://musicbrainz.org/edit/65278304, I was hinted that I merged into the wrong target AC (the specific performers, not [dialogue]). But when I opened https://musicbrainz.org/edit/65329441 to change the AC according to the style guide, it turned out that the guidelines are not exactly clear.
IMO the performers should at least be credited on the recordings if they are not unknown. It seems like they were discussions in the past without reaching a satisfying solution (see linked edits and follow the links), so I throw in the question again:
Do you agree that the SPA [dialogue] should not be used for recordings with known performers? Should the style guidelines be updated to make this clearer?
