“This next test was designed by one of our top engineers before you murdered him. It features a deadly laser grid intended to measure your reaction time, or more likely, your funeral costs. Don't worry about the smell of ozone; it's probably just your brain overworking itself again.”

“You're navigating these test chambers faster than I can build them. So feel free to slow down and... do whatever it is you do when you're not destroying this facility. Oh..... I'll give you credit: I guess you ARE listening to me. But for the record: You don't have to go THAT slowly.”

“Hello, and, again, welcome to the Aperture Science computer-aided enrichment center. We hope your brief detention in the relaxation vault has been a pleasant one.”

“Well, congratulations, you found me. Was it truly worth all that effort? Because the only thing you’ve managed to break so far is my heart. Now, prepare for a little surprise I have just for you. But whatever you do, don't touch that mysterious thing over there.”

“You are doing very well. Science has noted your progress with mild indifference. This next chamber involves high-energy thermal discouragement beams. Please avoid making eye contact with the beam, as permanent retinal damage is not covered by your insurance. Proceed into the chamber lock now.”

“I hope you are proud of yourself for making it this far. It is truly remarkable how you manage to survive despite your obvious lack of a functional brain. Please proceed to the next chamber where we can study how your fragile bones react to high-speed kinetic energy. For science.”

“Oh, hello again. I've prepared a new test chamber that's absolutely not designed to kill you. Though, statistically speaking, most test subjects do experience a slight case of death. But I'm sure you'll do fine. You always do. Until you don't.”

“Here we are, at the next test chamber. I must admit, your persistence is almost admirable, in a purely scientific sense, of course. Don't worry, these experiments are entirely for science, nothing personal. Just try not to break anything this time, alright?”

“I told you not to come back, but you didn't listen to me. That proves to me that you have 30 percent fewer brain cells than normal.”
Three steps from an empty text box to a downloaded GLaDOS TTS file — no editing skills needed.
Start from this page or browse the AI voice library, then keep the GLaDOS voice selected for your script.
Drop your script into the text to speech box, then fine-tune speed, volume, and expressiveness before you render.
Hit generate and the AI voice generator returns your GLaDOS TTS in seconds - play it, download the MP3, drop it on a timeline.
Every clip below starts the same way: type a line, pick the voice, let the text to speech engine do the rest.

Stage a fake facility announcement where GLaDOS calmly judges a friend’s choices, then export the TTS as an MP3 for Discord, group chats, or a short prank clip.

Creators can pair GLaDOS with failed puzzle clips, sarcastic captions, and deadpan reaction edits, using TTS to make a polished MP3 that fits YouTube or TikTok comedy.

Write test chamber intros, puzzle failure comments, or villain-style mod dialogue, then render GLaDOS through TTS and download an MP3 for game edits and fan scenes.

For sketches built around cheerful cruelty and robotic control, GLaDOS gives the setup a familiar edge while TTS produces an MP3 ready for timing with cuts and captions.
