What you’ll be able to do

You can take a script, whatever it’s for, a video explainer, a podcast intro, a training module, and turn it into a proper narration without hiring a voice actor or booking a studio. You paste text in, pick a voice, and get an audio file out. That’s it, really. No microphone, no soundproofing, no awkward retakes at 11pm because you fluffed a line.

It won’t sound exactly like a human every single time, but it’s got a lot closer than people expect. Good enough for most explainer videos, YouTube content, internal training, podcast intros. Good enough that your audience probably won’t clock it unless you tell them.

Before you start

The biggest mistake people make isn’t picking the wrong tool. It’s handing over a script that was written to be read, not heard.

Scripts written for the eye have long sentences, semicolons, clauses stacked on clauses. Scripts written for the ear are short. One idea per line. Contractions everywhere, because that’s how people actually talk. “It is” becomes “it’s”. “Do not” becomes “don’t”. Read your script out loud, right now, before you touch any AI tool. If you run out of breath partway through a sentence, so will the narration.

While you’re reading it aloud, mark it up. Where do you pause? Where would you naturally stress a word? Underline the name that’s tricky to pronounce. Circle the acronym you’re not sure the tool will say properly. This bit takes ten minutes and saves you a dozen regenerations later.

You don’t need special software for this. A printout and a pen works fine. So does a notes app if you’re that way inclined.

Get set up

For this kind of work, ElevenLabs is the tool I’d point you to first. It’s built specifically for AI voice-over: you paste in a script, choose from a large library of voices across lots of languages and accents, adjust how stable or expressive the delivery is, and it hands you back an audio file. It can also clone a voice from a sample recording, though that only ever means your own voice, or someone else’s with their explicit written permission. It offers dubbing into other languages too, if your project needs that.

There’s a free tier with a monthly allowance of characters, and paid plans that raise that allowance and unlock commercial use. I won’t quote numbers here because they change, so check elevenlabs.io/pricing before you commit to anything.

That said, ElevenLabs isn’t the only option, and it might not be the right one for you.

If you’re making quick social clips, the built-in text-to-speech inside CapCut or Descript will do the job without you leaving the editor. Less control over voice quality, but it’s fast and it’s already there. If you’re a developer building something at scale, Azure Speech and Google Cloud Text-to-Speech give you programmable voices, but they’re aimed at people writing code, not people who just want an MP3. Speechify and NaturalReader are reader apps, decent if you want something read aloud quickly, but you don’t get much say over tone or pacing. And then there’s the free option that’s always been sitting on your computer: the system voices on Apple and Microsoft devices. Free, always available, and they sound like it.

Signing up for ElevenLabs takes a few minutes. Go to elevenlabs.io, create an account, verify your email, and you’ll land on a dashboard with a text box waiting for your script. That’s genuinely most of the setup.

Try it yourself

Right, script in hand, account set up. Time to actually make something.

Paste a short section of your script into the text box first, not the whole thing. Test with a paragraph before you commit a full ten-minute explainer to one voice choice.

Welcome to the show. Today we're talking about something most people get wrong: how to actually finish the projects they start. I've made every mistake in the book, so let's get into it.

Pick a voice from the library that matches the tone of your project. A podcast intro probably wants something warmer and more relaxed than a corporate training video. Have a listen to two or three previews before settling.

Then look at the settings for stability and expressiveness. Higher stability keeps the voice consistent and calm, which suits factual or instructional content. Lower stability, more expressiveness, gives you something livelier, which suits story-driven or emotional content. There’s no universal right answer here, it depends what you’re making.

Generate a take. Listen to it properly, all the way through, not just the first ten seconds. Then generate two more with small tweaks, maybe a different stability level, maybe a different voice entirely, so you’ve got three options to compare rather than one you’re stuck with.

Here’s a prompt structure that works well if you’re using an AI writing tool like ChatGPT or Claude to prepare the script before it goes into ElevenLabs:

Rewrite this script so it sounds natural when read aloud. Use short sentences, contractions, and one idea per line. Keep the meaning exactly the same. Flag any words that might be hard to pronounce.

[paste your script here]

And if you’ve got tricky names or jargon in there, you can ask for a phonetic version too:

Give me a phonetic spelling for these words so a text-to-speech tool pronounces them correctly: [list the words]

Once you’ve picked your favourite take, export the audio file. ElevenLabs will give you a downloadable file you can drop straight into your video editor alongside your visuals, or use as-is for a podcast intro.

Check the result

Don’t just accept the first output because it sounds fine on first listen. Run a few actual checks.

Play it back next to your video, if you’ve got one, and ask whether the tone matches. A cheerful upbeat voice over a serious topic feels wrong, and you’ll notice it immediately once picture and sound are together.

Listen specifically for names, brand terms, and any jargon. This is where AI voice-over most often trips up. If a name comes out wrong, that’s your cue to go back and spell it phonetically in the script, then regenerate just that section.

Check the pacing. Does it rush through important points? Does it linger oddly on a comma? Small script tweaks, adding a line break, adding a comma where there wasn’t one, changes rhythm more than you’d think.

Finally, drop the exported file into your actual video editor and see how it sits against music, sound effects, or captions. Something that sounded perfect in isolation can feel oddly loud or quiet once it’s mixed with everything else.

If it doesn’t work

If the narration sounds flat or robotic, the fix is often the script, not the tool. Go back and shorten your sentences. Read it aloud again. AI voices tend to follow the punctuation and structure you give them fairly literally, so a script that reads awkwardly on the page will sound awkward out loud too.

If a specific word keeps coming out wrong, spell it phonetically directly in the script rather than fighting the tool’s pronunciation engine. “Featurette” might need to become “fee-cha-ret” in the text box, purely for the read, then you swap it back for the version you keep on file.

If the voice just isn’t right, try a different one from the library rather than tweaking settings endlessly. Sometimes the voice itself is the mismatch, not the stability slider.

On privacy: don’t paste anything into a voice-over tool that you wouldn’t be comfortable with living on a server somewhere, especially unreleased business information, personal data about other people, or anything under an NDA. Treat the text box the same way you’d treat an email to a stranger.

And on permission: never clone a voice that isn’t yours, or one you don’t have explicit written permission to clone. Don’t imitate a named presenter or actor, even if you can. Check the commercial terms on whichever tool you’re using before you put the audio into an advert or a paid product, and if there’s any chance a listener could mistake the narration for a real human speaking live, say somewhere that it’s synthetic. It’s a basic decency thing as much as a legal one.

Keep exploring

If you’re building the visuals to go with this narration, have a look at “How to get AI to make a video”. If you just need existing text read aloud quickly, without the full voice-over workflow, “How to get AI to read text out loud” covers that. And once you’ve got picture and sound both sorted, “How to get AI to edit a video” walks through putting it all together.
