|For the myth in GTA IV, see Evil Voice (GTA IV).|
These rumors were initially originated from GTA Vice City, when players started to hear sounds that are quite similar to the evil voices heard in GTA IV. Players hear these sounds when they get wasted in cars. Technical investigations have revealed that during combustion, car engine sounds like a shriek which is strangely similar to the evil voice heard in GTA IV. However, in reality, it's not an evil voice but an audio file for specific vehicle purposes.
