Type a script and get a natural-sounding MP3 voiceover for your Reels, TikToks, and Shorts: eight voices, adjustable pace, instant download. It speaks the words youwrite; it never clones a real person’s voice.
Generates speech from the script you type — it never clones a real person’s voice or reads anyone else’s content. The script is sent to the speech service to render the audio; nothing is stored.
A voiceover for your script, without the recording setup
Faceless videos, slideshow narration, ad reads, and hook-driven Reels all need a voice, but not everyone wants to record their own, and re-shooting a single flubbed line costs more time than the clip is worth. This tool reads the script you type in a natural-sounding synthetic voice and hands you a clean MP3 to drop into your timeline. Rewrite a line, regenerate, done. No mic, no room tone, no retakes.
The deliberate limit: it works on yourwords. It will not clone a real person’s voice from a sample, and it won’t narrate text you don’t own. That keeps you clear of the consent and copyright problems that come with voice-cloning tools. and it means the audio you make is genuinely yours to publish.
How to write a script that sounds natural
Text-to-speech reads exactly what you give it, so the script does most of the work. A few habits that make synthetic delivery sound human:
Write the way you talk. Short sentences. Contractions. The odd fragment. Read your draft aloud first. If it trips your own tongue, it’ll trip the voice.
Punctuate for breath. A comma is a short pause; a period is a longer one. Break a run-on into two sentences and the pacing fixes itself.
Spell tricky words phonetically. Brand names and acronyms can read oddly, so write “S-E-O” or a rough phonetic spelling if the literal one sounds wrong.
Front-load the hook. Short-form lives or dies in the first two seconds, same rule as the caption. Need to check where a caption folds? Our caption previewer shows you.

How it works
How the voice generator works
1
Write or paste your script
Type the words you want spoken: a hook, a caption, a 60-second voiceover. It's your text, not anyone else's content.
2
Cast a voice
Pick from eight personas, from a bright, upbeat read to a calm narrator or a news-anchor delivery. Match the voice to the video's mood.
3
Set the pace
Nudge the speed slider faster for snappy hooks or slower for explainers. The character counter estimates how many seconds of audio you'll get.
4
Generate and download
Get a clean MP3 you can preview in the page, then download and drop straight into your editing timeline.
Got the audio? The script usually wants to live on as a caption too. Turn it into a longer post or thread with the thread splitter, or plan where it runs with a content calendar. New to narration? Our guide to adding a voiceover covers when to use one and how to write a script that sounds natural.
Voiceovers for TikTok, Reels, and Shorts
The generator makes one clean MP3 from your script. What changes per platform is the script length and how the audio sits in the edit:
TikTok voice generator
For a TikTok voiceover, keep the script tight, because a 30–60 second clip is roughly 75–150 spoken words, and front-load the hook into the first two seconds. Generate the MP3, drop it on its own track, and cut your b-roll to the narration rather than the other way round.
Instagram Reels voice generator
Reels are watched muted first, so a generated voiceover only does half the job on its own, so pair it with on-screen captions of the same script. A warm, conversational voice tends to fit Reels’ lifestyle feel better than a hard news-anchor read.
YouTube Shorts voiceover
Shorts reward a clear, even delivery that carries an explainer or list video. Write for the ear, spell out any brand names or acronyms that might read oddly, and keep the pace unhurried, because speed-reading a long script is what makes a voiceover sound rushed.
Faceless videos, ads, and slideshows
Beyond short-form, the same workflow covers faceless YouTube videos, ad reads, slideshow narration, and podcast intros, anywhere you’d normally record a voiceover but would rather type the script and skip the mic.
Frequently asked questions
Is the AI voice generator free?
Yes. Generate voiceovers from your own scripts at no cost, with no login. Because every voiceover is real text-to-speech spend, free use is limited to 3 a day per visitor, with a per-script length cap, and the cap resets the next day. Kadenzo Studio members get more without a separate sign-up here: a trial account gets 10 a day and a paid plan gets 30 a day, as long as you are signed in to Studio in the same browser. For a steady production pipeline of long-form audio you'd want a dedicated paid TTS service, but for hooks, captions, and short video scripts this covers it.
Can it clone my voice or a celebrity's voice?
No, and that's deliberate. This reads your typed script in one of a fixed set of synthetic voices. It does not clone, copy, or imitate any real person's voice from a sample, and it won't read content you don't own. Voice cloning of a real person without consent is a legal and ethical minefield; this tool stays well clear of it.
Can I use it for TikTok, Reels, or Shorts voiceovers?
Yes, that's the main use. It works as a TikTok voice generator, an Instagram Reels voice generator, and a YouTube Shorts voiceover tool all at once: you write the script, pick a voice, and get an MP3 to drop into your editor. The only thing that changes per platform is the script: keep it short for a 30–60 second clip, and remember most short-form is watched muted at first, so pair the voiceover with on-screen captions of the same words.
What can I use the audio for?
Reels, TikToks, Shorts, faceless videos, ad reads, slideshow narration, podcast intros, anywhere you'd normally record a voiceover. The MP3 is yours to use commercially. The one rule is on the input: write your own script, don't paste copyrighted text you don't have the rights to.
How long can the script be?
Up to 1,000 characters per generation, roughly 80 seconds of speech, which is one tight short-form script. For a longer piece, split it into sections and generate each separately, then stitch them in your editor. The character counter shows your length and an estimated duration as you type.
Which voice should I pick?
Match the voice to the video's job. A bright, energetic read suits a fast hook or a trend; a calm narrator fits storytime and walkthroughs; a news-anchor delivery lands for finance and tech explainers; a warm, conversational voice works for reviews and lifestyle. When in doubt, the even, neutral educator voice is a safe default for any explainer.
Is my script stored anywhere?
To render the audio, the script text is sent to the speech service that generates the MP3. That's the one server step, the same as any text-to-speech tool. The text isn't saved to an account (there are no accounts) and the audio isn't kept after it's returned to you. Don't paste anything sensitive: no passwords, no private personal data.
Why does it reject links and phone numbers?
Two reasons: a spoken-out URL or phone number sounds terrible in a voiceover, and the bigger one, blocking them keeps the free tool from being used to mass-produce scam and phishing scripts. If your script genuinely needs a web address, say something natural like "link in bio" instead.
