So here's an easy workaround for Conlanging. Instead of coming up with specific words and phrases, give your players a brief description of what their language sounds like, and a selection of word roots and common word root variants, that way, they can imagine it in the theater of their minds, rather than hearing you struggle through it verbally audibly. My example here is Orcish, a rough, brutish, unhappy language that sounds like grunting, screaming, hissing, and very primitive words, filled with slurs curses and insults.
