However, based on its spelling and common pronunciation patterns in English, here's a likely way to say it:
al-gah-lee-ah-rept
* al-: Like the first syllable of "alarm"
* gah-: Like "ga" in "garage"
* lee-: Like "lee" in "tree"
* ah-: Like "ah" in "father"
* rept: Like "rept" in "reptile"
It's important to note that this is just a suggestion, and the creator of the word may have intended a different pronunciation.
