Assuming the pronunciation of these parts are cove (as in a small sheltered bay), all (rhymes with Paul), chev (rhymes with lev as in levitation) and ski (as in the spot), maybe something like:
qov ‘ol chev SIy
This is far from perfect. It’s hard to get some of it because the sounds don’t exist in Klingon. The “a” sound in “all” and the “sk” sound in “ski” are hard to replicate with Klingon sounds.
You may want to go to https://hol.kag.org/page/sounds.html and look through the sounds of the language and figure out which come closest to the sounds you make when saying the name.
