Masks for talking heads
A talking head is a type of NPC in Fallout and Fallout 2. In these games, ordinary NPCs appear as normal game sprites in dialogues and have no voice; talking heads, in contrast, have fully animated, three-dimensional portraits, and fully voice-acted dialogue that has been lip-synched to the animation. In Fallout 3, Fallout: New Vegas and Fallout 4, every NPC (with a few exceptions) has at least a few voiced lines, so "talking heads" no longer appear.
Some of the voices for the talking heads were produced by well-known actors, such as Richard Dean Anderson from MacGyver and Stargate SG-1, and Michael Dorn who is known as Worf from Star Trek: The Next Generation.
