Aha, and right after I said that, I found it.
The game has such data recorded in racedata.txt.
Race # 369 is the new goblins, and the goblin sounds from soundassets.txt (3457, 1155-1158) are included in the many unnamed fields in racedata.txt for that race.
Parsing racedata.txt might be very interesting, when one can find some spare time for experimentation.
If you're wanting a reference of races, I have a race inventory available online:
