Steamworks voice chat in ue4

These days,I am developing a game that can voice chat with other players,so I search the steamworks document,I found that when I get the final voice data,I can’t use this type of data in ue4 (its type is void*,this kind of type isn’t allowed in ue4 macro),so I can only replicate this data by using steamworks’ p2p interface.But that’s not a problem.The real problem is that I want to play the voice data as sound cue,it should be in game world.So how to do that.
