Unidentified language (Star Tours)

This unidentified language was occasionally used by personnel of the travel agency Star Tours since at least a few months after the Battle of Endor, along with writing in Aurebesh, the High Galactic alphabet, and a written script. C-3PO occasionally used this language during his brief stint at Star Tours around the time of the Nagai-Tof War.

Behind the scenes
Unsurprisingly for an attraction at Disneyland Paris, the Paris version of Star Tours features speech in French. When the park attraction opened and was revealed to feature a bilingual option, C-3PO's actor, Anthony Daniels supplied his lines in both English and French.
