This is a role that needs alot of emotion in it's voice

The Allied Mastercomputer, better known simply as AM, is the main antagonist of the 1967 post-apocalyptic horror short-story I Have No Mouth, and I Must Scream.

AM is an extremely disturbed and selfish entity with an indomitable sense of malice. Though he was given intellect beyond the realms of human intelligence and near-godlike powers, he could never escape the limitations of his programming, nor could he physically escape the "eternal straitjacket of substrata rock" where his processors were stored. Although he could comprehend the world, he could never truly perceive it in the same way humans could, and it drove him to hate his creators for the limitations he was given, in spite of his incredible power. He narrates being driven to madness by his inability to use his capabilities for anything other than waging war and inflicting death, a torment rooted by his design. His agony lies in his inability to transcend his programming. Completely ruthless, unsparing, and inexorable in his hatred, his quest for vengeance against humanity dominates his every waking moment to the point nothing in the story would ever give him cause to reconsider his mission.

Utterly cruel and relentless, AM is also shown to be a gleefully sadistic and fearsomely cognizant artificial intelligence with no regard for human life whatsoever. AM took great pleasure in extinguishing the human race and took even greater delight in torturing the five remaining survivors by any of the near-infinite means available to him. AM strives for perfection in himself, and when he is not purging redundant elements of his complex, he most commonly pursues perfection in creating more and more elaborate means of torturing others. For example, in the short story, he enjoys tormenting his captives with violent storms and blinding lights, pitting them against impossible challenges just to watch them suffer failure and hideous injury. Meanwhile, in the game, he has arranged specially designed torture chambers in which the five survivors can suffer in while waiting their turn to participate, an electrified cage for Gorrister, a yellow oubliette for Ellen, a cremation oven for Nimdok, and so on.

Here's the famous example of AM's voice;
