Talaxian language
From Memory Alpha, the free Star Trek reference
The Talaxian language is the primary language spoken by the Talaxians.
Nearly all Talaxian proper nouns contain the letter x (pronounced ks), this may be an honorific sound in the Talaxian language or merely a very common sound that seems to occur everywhere.
Talaxian writing resembles strings of long and short rectangles with curvy lines cut out of them; these lines are usually written in horizontal and vertical blocks. (VOY: "Homestead")
