Sorry, my bad. This is the right file: https://drive.google.com/open?id=0B7SpUfi4PH7aZEVXaGxKeXdGanc
This was tested in 4.9, some modifications may be needed for 4.11, let me know how it goes.
I didn’t have to use soundwaveprocedural to play the data, this was handled directly by VoiceEngineImpl.cpp (haven’t checked if this changed in in 4.11 though)
Also, if you found a way to properly integrate the generation of the opus libraries please share
