"SHODAN (Sentient Hyper-Optimized Data Access Network) is a fictional artificial intelligence and the main antagonist of the cyberpunk first-person shooter/role-playing games System Shock and System Shock 2. She is voiced by game writer and designer Terri Brosius.
She is characterized by her megalomania and chaotic, discordant speech. Her words are accompanied by stuttering, fluctuating voice pitch, shifts of timbre, and the presence of three voices speaking the same words with the constituent voices alternately lagging behind and leading ahead, as well as computer glitches resembling a sound card malfunction."
