How do I choose random audios to play?

Hello, so i want to create an optimized and working system that chooses a random audio, then another one without repeating the last audio played. I'm making an Rpg based chat system with simple voices and it's variations like Undertale, but i don't know how I can do it properly. Any help would be grateful.

You could use advanced random to generate a shuffled list of numbers called a permutation table and the numbers relate to certain tracks
