Robot Voice Generator
Robot Voice Generator
Type text, pick a robot effect, get an MP3. This robot voice text to speech tool needs no microphone. Four effects work with all 30 voices and more than 130 languages, and you can hear each one before you sign in.
How it works
Make a Robot Voice in Three Steps
1Step 1
Type your text
Turn up to 5,000 characters of text to robot voice, in any language. Short lines work best: a countdown, a warning, a greeting.
2Step 2
Pick an effect and a voice
Tap an effect to hear it. Robotize pulls the pitch flat, Ring modulator buzzes, Android sounds metallic and Deep robot goes low and slow.
3Step 3
Generate and download
Most lines are ready in seconds. Keep every take in your history, and download MP3 or WAV on a paid plan.
What you get
A Real Robot Sound, Not Just a Flat Read
Asking a normal AI voice to sound like a robot only makes it read slower. This robotic voice generator uses effects that change the sound itself.
Four robotic voice effects
Robotic text to speech usually means a flat read. Robotize goes further and locks the pitch into one note, the classic robot sound. Ring modulator adds a buzzing sci-fi villain growl. Android sounds like it's coming from inside a machine. Deep robot is lower, slower and heavier.
Robot TTS in any language, any voice
The effect runs on the finished audio, so robot text to speech works with all 30 voices and more than 130 languages. Type in Spanish or Japanese and the robot speaks Spanish or Japanese.
Robot speech with timing you control
Add pauses and sounds where you want them, or set the pace to slow for that deliberate machine rhythm. Effects cost no extra credits.
Yours to download
Every take stays in your history. Paid plans download MP3 or WAV for videos, games and other commercial projects.

Robot Voice Questions
Type your text, choose one of the four effects and a voice, then press Generate speech. Tap an effect's icon first to hear what it sounds like. Most short lines are ready in a few seconds.
Type what you want said and pick an effect. This is robot text to speech, so you don't need a microphone or any audio to start with, and the robot talks for you in the voice and language you choose. Making your own recording sound robotic takes a robot voice changer, which this tool isn't.
All three. People use those names for the same job: you type text and get speech that sounds like a machine. Here an AI voice reads your text and an audio effect turns it into an AI robot voice, so it also works as a text to speech robot or a robot voice text reader for anything you paste in.
Lacuna is free to start. All the effect samples and examples play without signing in, and free accounts get 120 credits a month, about 2,400 characters of speech. It costs 5 credits per 100 characters, and effects don't cost extra. Downloads come with paid plans.
Yes, on a paid plan. Every take is saved in your history and downloads as MP3 or WAV. Listening is always free.
Robotize pulls the pitch flat, which is the classic robot sound. Ring modulator adds a buzz, like a sci-fi villain. Android has a metallic, inside-a-machine ring. Deep robot lowers and slows the voice for a heavier sound.
In our tests, writing "sound like a robot" in the instructions didn't flatten the pitch at all; the read only got slower. A robot voice comes from an audio effect applied afterwards, which is what this tool does.
No. This tool starts from text and doesn't process recordings. To tune your own singing hard enough to sound robotic, try Autotune Online.
Partly. Robotize, Android and Deep robot set the pitch themselves, so the voice you pick mostly changes the texture. Ring modulator keeps the voice's own pitch, so a female voice stays female. Use Direction to describe the attitude, like cold or cheerful.
Not in one take, because the effect applies to the whole audio. Generate the robot lines and the human lines separately and put them together in a video or audio editor.
More than 130. Write the text in the language you want and the robot speaks it; there's no language menu to set.
Yes, on a paid plan. Audio you make while subscribed can go into videos, games, ads and other commercial projects.
