GLaDOS turns the language of helpful systems into passive-aggressive commentary. Begin with a status update, a test instruction, or a congratulation, then let the final clause undermine the listener's achievement. The contrast between calm delivery and unkind content makes this voice useful for puzzle narration and fictional assistant messages.

Writing guide
How to write for GLaDOS
Do this
- Use the vocabulary of tests, measurements, and system notices.

- Separate instructions with full stops to preserve the clinical rhythm.
Avoid this
- Heavy distortion on top of the model can make a robotic voice unintelligible.
- Typing sound-effect descriptions will not reliably create game interface sounds.
