Todays patch includes a number of improvements to the way sounds work in game. In particular regard to NPCs and interacting with NPCs.
A number of the NPCS were previously scripted with a generic series of sound effects which gets repetitive. Work is ongoing to update these to be a little more enjoyable.
A number of monsters have also had new sound effects added as all too often I simply went with "Bear" attack noises .... lazy but this is why the game is currently going through early access to iron out these last few kinks.
Speaking of kinks, a glitch which caused male players to use the female voice has been fixed.
Please note this is simply Part 1 of a series of patches to correct the sound effects.
