Learning to Speak
This is my first fanfic! I came up with the idea whilst playing Portal 1; it is set during the events of that game. No pairings, so don't worry!
GLaDOS watched the test subject as she made her way through Chamber 16. She wore a look of concentration and determination on her face- something you would need when navigating through a chamber filled with deadly turrets. GLaDOS chuckled as she noticed that the test subject jumped away from the turret she had just knocked down the stairs. It faded away with a final "I don't hate you".
Suddenly, she had a bright idea. The test subject had suffered damage to her vocal cords leaving her mute. Whilst this was good (Or at least to the AI because she didn't have to put up with human whining- in her opinion, a very bad human trait), it was slightly unnerving that she never made any sort of sound, not even cries of pain when hurt.
The turrets can speak. Perhaps there's some way to transfer the speech processor into the human...no, it would never work. Besides, with only her currently running the facility, and little to no funding resulting from Aperture's many failed experiments in the past and CERTAIN OTHER SCIENCE COMPANIES, there would be no way they could pull this off, let alone successfully.
Anyway, why this test subject? Why would she waste her time on THIS particular one? GLaDOS sighed. She wasn't smarter or more athletic than anyone else. All she really had was her abnormal stubbornness and that wasn't exactly a trait to be proud of. Still, she was more resilient than any other test subject; she never gave up, even in the "impossible" test. But what benefit would giving this mute girl a voice have?
Frowning, GLaDOS turned her attention to a lab where robots were busy on construction of some new testing elements. Suddenly, she had a brainwave. She may not have human scientists anymore, but she had an army of robots on her side. Whilst thinking about this, GLaDOS felt a wave of panic rush over her as she remembered.
