Like any game, voice actress Courtnee Draper was required to record a series of grunts, sighs, and other non-sequitur expressions for her interactions with the world. Where most games would be content with a single large database of these sound effects, the team at Irrational had several different versions of these audio files recorded as Courtnee finished her most emotive sessions ensuring that they'd have a wider sampling of "generic" audio files that more appropriately matched the character's emotional state as the game progressed.
