for my Experimentation i decided to record voices for the NPC‘s i when in to a quiet room in college and began making phrases for the npc’s first up was the cave men for them i felt like they would mumble and growl alot not making any actual words sines they are not involved enough to make speech this is what i came up with https://youtube.com/shorts/h9czlIGivs4?feature=share
i also mad sounds for all the NPC’s walking around the sounds i made can be used for all the Npc’s and even the players character i made two different sounds for the npc’s.
I also made sounds of doors opening and close for experimental research to do this i used the college class doors and i made sure there was no other sounds here is another sort clip of what it sounds like
