How to Sound Like a Robot (or a Borg Drone)
The word robot was introduced in 1920 by Czech writer Karel Čapek in his play R.U.R. (Rossum's Universal Robots). Čapek credited his brother Josef with the word, which comes from the Czech robota — forced labour.
A century later, robots have a recognisable way of speaking in fiction. Here's how to sound like one.
The Counterintuitive Truth: Real Computers Taught Robots to Sing
One of the most famous robot voice moments came from real computer science. In 1961, researchers at Bell Labs programmed an IBM 7094 to sing "Daisy Bell" using speech synthesis. Arthur C. Clarke saw a demonstration, and HAL 9000 sings the same song as it shuts down in 2001: A Space Odyssey (1968).
We call this lab-to-screen voice: fictional robot speech inspired by real experiments.
Robot Speech Rules
1. Flat Tone
Remove emotion. Keep pitch even.
2. Precise Wording
- "Affirmative" instead of "yes"
- "Negative" instead of "no"
- "Processing" instead of "hmm"
3. State the Obvious
"You appear to be experiencing sadness."
4. Report Status
"Battery at 12 percent. Initiating power-saving mode."
5. Literal Interpretation
Human: "Break a leg!" Robot: "Why would I damage your limb?"
We call this literal logic humour: comedy from machines taking idioms at face value.
Robot Phrase Makeover
| Human | Robot |
|---|---|
| Hi! | Greetings, human. |
| I'm hungry. | Energy levels critical. |
| I don't get it. | Error: input not recognised. |
| Let's go! | Initiating departure sequence. |
| Good night. | Entering sleep mode. |
Famous Robot and AI Voices
| Character | Famous line | Style |
|---|---|---|
| HAL 9000 | "I'm sorry, Dave. I'm afraid I can't do that." | Calm, polite, unsettling |
| The Borg | "Resistance is futile." | Collective, monotone |
| Daleks | "Exterminate!" | Harsh, electronic |
| C-3PO | "We're doomed." | Anxious, formal |
| R2-D2 | Beeps and whistles | Non-verbal |

How to Sound Like a Borg Drone
The Borg speak as one collective voice:
- Use "we", never "I."
- State outcomes as inevitable.
- Describe others as resources.
"We are the collective. Your coffee will be assimilated. Resistance is futile."
We call this plural certainty: speech with no individual doubt.

Where Robot Voices Came From
- Vocoder: Developed by Homer Dudley at Bell Labs in the 1930s, it later shaped robotic voice effects in music and film.
- Ring modulators: Used for the Daleks' harsh voices in Doctor Who.
- Actor performance: Many robot voices are simply actors speaking flatly.
What Experts Say
Human-computer interaction researchers note that modern AI assistants are deliberately designed to sound warm and human — the opposite of classic sci-fi robots. Researchers studying the "uncanny valley" suggest voices that are almost human can feel more unsettling than obviously robotic ones.
Where Robot Speech Is Heading
Real AI voices now sound almost indistinguishable from humans. We predict the classic flat "robot voice" will survive mainly as a retro style — like pixel art — used in games, comedy, and nostalgia, because real machines no longer sound like robots at all.
