While we enjoy working in the fantasy world of the Klingon race as real, it’s good to keep in mind that Okrand works with actors, directors, and makeup artists (the the prosthetic teeth that Klingon actors often, but not always wear), and whatever shows up on the movie screen is always right.
Only if Okrand explains it. If he doesn't explain it, then any deviation from what he has explained may simply be an individual's idiosyncrasy or error.
For instance, in Star Trek V, Vixis says tlhIngan 'aH wa'
vub'e'. She mispronounces 'oH. From just this, you
can't conclude that 'aH is an acceptable alternative to 'oH
or that some cohorts find it so or anything of the kind.
Okrand can make up rules for syllabic emphasis, but if an actor mauls the pronunciation, emphasis, or natural speech rhythm, it becomes canon.It becomes a canonical example of something that someone has said. That doesn't mean we should derive rules from it. Have you never misspoken or mispronounced something?
taH pagh…. [long pause] … taHbe’!
Here's the clip: https://youtu.be/HsCVuO1yeJc?t=25
There's no long pause there. And if there were, what would that
mean? That you have to put a long pause between the pagh
and the taHbe'? Really?
