Voice type
Robot Voice Generator
Speech studio
34 voices · 18 languages
Turn text into a flat, synthetic read for game characters, sci-fi narration, and announcements — then download the MP3. Free, no sign-up, commercial use included.
How it works
Three steps, about a minute
- 1
Paste or write your text
Drop in a script, a paragraph, or a whole article. Longer text is split into parts automatically and joined back into one file.
- 2
Pick a voice and preview it
Almost every voice has a preview you can play before spending anything, paid ones included. Filter by language, then hear two or three before committing.
- 3
Generate and download
Audio comes back in seconds as MP3 or WAV, with a commercial licence on every tier — including the free one.
Examples
Hear it on real scripts
Every clip below was generated here on the free tier — no account, no credits. Play one to hear the voice on that kind of writing, or load the script into the generator and make your own version of it.
YouTube intro
Opens a video without the "hey guys, welcome back" throat-clearing.
“Three years ago, this cost four thousand dollars and a studio. Today it costs nothing and takes about a minute. In this video I'll show you exactly how — no jargon, no upsell, and every step is one you can copy while you watch.”
YouTube outro
Closes the loop and asks for one thing, not four.
“That's the whole method. If it worked for you, the next video takes it further — same tools, bigger project. And if it didn't, tell me where it broke. I read every comment, and half of these videos exist because someone got stuck.”
TikTok hook
The first three seconds, where the scroll is decided.
“Stop scrolling. You've been doing this wrong your entire life, and nobody told you, because the right way takes four seconds and looks like cheating. Watch.”
Included
What you get
- Free without an account
- Thousands of characters a day as a guest, no sign-up and nothing to install. An account raises the limit; it is not a gate on the tool.
- Commercial use included
- Monetised videos, client work and ads are all fine on every tier. You own what you generate.
- MP3 and WAV export
- MP3 for editors and uploads, WAV where you need uncompressed audio. Speed is adjustable from 0.75× to 1.5× on engines that support it.
- Long text, one file
- Text past the per-request limit is split at sentence boundaries, generated in order, and stitched back into a single download.
- Voices across 18 languages
- Several languages are read by voices trained on that language rather than an English voice reading foreign words — the difference is audible immediately.
- Credits that never expire
- Premium and ultra voices are billed in credits. One-time packs never expire; monthly plans refill every billing cycle instead.
Two different things people mean by "robot voice"
Searches for a robot voice generator split into two requests that need completely different tools, and knowing which one you are after saves a lot of wasted time.
The first is the modern machine voice — the even, unemotional read of a smart speaker, a ship computer, or an AI character in a game. That is a speech-generation problem, and it is what this page does well.
The second is the retro sound: Speak & Spell, vocoder, the buzzing metallic voice of 1980s science fiction. That is not generated speech at all. It is an audio effect layered onto an existing recording, which is why no text-to-speech model produces it directly. The section below covers how to get there in two steps.
How to get a machine-sounding read
Modern neural voices are trained to sound human, so the work here is removing warmth rather than adding an effect. Most of that happens in how you write the line, not in the settings:
- Start with Adam — the flattest of the free voices, and the least emotionally coloured
- Drop every contraction: "do not" and "cannot" read as machine, "don't" reads as person
- Keep sentences short and declarative; a machine states, it does not build an argument
- Delete exclamation marks and question marks where you can — both add human pitch movement
- Use commas to force even, metered pauses, which is what makes a read sound clocked rather than spoken
- Prefer formal vocabulary: "proceed" over "go ahead", "affirmative" over "yeah"
- Keep the speed at 1.0×; uneven pacing is the strongest human tell there is
Getting the retro vocoder sound
If you want the classic buzzing robot rather than a clean computer voice, generate the line here first and then process it. The flat read you produce above is the right input, because effects applied to an already-expressive performance sound muddled.
Download the MP3, open it in any free audio editor — Audacity is the usual choice — and apply a vocoder, bitcrusher, or ring modulator. A small amount of pitch shifting downward and a short echo will get you most of the rest of the way.
This is a two-step workflow rather than a one-click button, and any site claiming to generate that sound directly is almost certainly applying the same effect after generating speech, just without telling you.
Cost and licensing
The free voices cost zero credits. Guests generate up to 5,000 characters a day without an account, and a free account doubles that to 10,000. Every generation — free tier included — comes with a commercial license and no watermark, so the audio is cleared for released games, monetized channels, and client work.
The paid tiers exist for range rather than for permission. A robot read does not need emotional nuance, which makes this one of the few cases where the free voices are not a compromise at all: flatness is the goal, and Adam delivers it.
