headcanon: vulcans become convinced that humans are physically incapable of saying vulcan names correctly, so they just Deal With It. until one day someone runs into a human who speaks hebrew and she gets their name right on the first try

“my clan name contains phonemes that humans cannot pronounce, you do not need to-”
“what? it’s just s'chn t'gai, right?”
“[long pause] …yes. [takes out roster of vulcan crew members] do these next”

she ends up with a group of Deliberately Not Excited vulcans standing around her listening intently to her saying names
“spock”
“you pronounced that admirably”
kirk in the background: “THAT’S HOW I SAY IT”
“no it is not, captain”
