You can make an AI voiceover for free in about five minutes: paste your script into a free text-to-speech tool, pick a voice, adjust the speed, and export an MP3 or put it straight onto your video timeline. For most people the best free option is Microsoft Clipchamp, because its AI voiceover is free for every user and sits right inside a video editor. If you want the most human-sounding voice and don’t need commercial rights, ElevenLabs’ free plan is the one to try.
This guide walks through the whole process step by step, compares five free tools, and explains the part most tutorials skip: which free voiceovers you are actually allowed to use on a monetized YouTube channel or a client project.
Quick answer: the 5 best free ways to make an AI voiceover
We ranked these tools on four things: how much you get for free, how natural the voices sound, whether free output can be used commercially, and how easy it is to get the audio onto a video. Every fact below comes from each tool’s official site or help center, checked on 2 November 2026.
| Rank | Tool | What you get free | Commercial use on free plan | Best for |
|---|---|---|---|---|
| 1 | Microsoft Clipchamp | AI voiceover free for all users, 400 voices, 80 languages | Check Clipchamp’s terms for your use | Voiceovers for videos, in one editor |
| 2 | CapCut Text to Speech | 200+ AI voices, MP3/WAV/AAC/FLAC export | Yes, per CapCut’s FAQ (follow its terms) | Shorts, Reels and TikToks |
| 3 | Google AI Studio (Gemini TTS) | 30 prebuilt voices, style controlled by your prompt | Review Google’s terms; free-tier data may be used by Google | Expressive narration and tone control |
| 4 | ElevenLabs Free | 10,000 credits a month | No; attribution required | The most realistic voices for personal projects |
| 5 | Kokoro-82M (open source) | Unlimited, runs on your own computer | Yes, Apache 2.0 licence | Developers and offline use |
Before you start: write a script that sounds good out loud
The voice is only half of a good voiceover. The other half is the script, and AI voices expose weak writing fast. A few habits make any free tool sound better:
- Write short sentences. Long sentences with several commas make AI voices run out of rhythm. Aim for 8 to 15 words.
- Spell out tricky words. Write “N eight N” instead of “n8n”, “S S A” instead of “SSA”, and “twenty twenty-six” if a voice reads the year strangely.
- Use punctuation as direction. A full stop gives a clear pause; a dash or ellipsis gives a shorter one. Most tools follow punctuation more reliably than any “pause” setting.
- Read it aloud once yourself. (If your video is a tutorial, record the on-screen part first with one of the best free screen recorders for PC, then time the script to the footage.) If you stumble, the AI voice will sound awkward at the same spot.
- Time it. Natural narration runs at roughly 130 to 160 words per minute, so a 45-second Short needs about 100 to 120 words.
If you are writing the script with AI, rewrite the first line yourself. The first two seconds decide whether people keep watching, and generic AI openers are easy to skip. Our guide on writing content people actually read covers the same principle for text.
1. Microsoft Clipchamp: the best free AI voiceover for videos
Clipchamp is Microsoft’s browser-based video editor (it also ships with Windows). According to Clipchamp, “the AI text to speech feature is free for all Clipchamp video editor users”, with 400 voices in 80 languages and speed control from 0.5x to 2x. Microsoft’s support page says the feature runs on Microsoft Azure AI Speech, which explains why the voices are clear and consistent.
How to make an AI voiceover in Clipchamp
- Open Clipchamp in your browser or the Windows app and create a new video.
- Click the Record & create tab on the toolbar, then choose Text to speech. The text-to-speech panel opens on the right.
- Choose a language, then a voice. Use the preview button to hear each one.
- Open the advanced settings if you want to change the pitch or pace.
- Paste your script into the text box, click Preview, then Save. The voiceover lands on your timeline and in your media library.
- Export the finished video, or save the voiceover on its own as an MP3.
Tip: Microsoft notes that the character limit per text-to-speech item varies by language. For long scripts, split the text into paragraphs and create one voiceover item per paragraph. That also makes it easier to fix one line later without regenerating everything.
Pros: free for all users, huge voice and language choice, no separate audio tool needed, easy timeline editing.
Cons: voices are clean but less emotional than ElevenLabs; you need a Microsoft account.
2. CapCut Text to Speech: best for Shorts, Reels and TikTok
CapCut’s online text-to-speech tool advertises more than 200 AI voices, with controls for speech rate, pitch, volume and fades, plus background noise removal. You can export audio as AAC, FLAC, MP3 or WAV. CapCut also offers a voice clone built from a recording of your own voice.
The detail that sets it apart for creators: CapCut’s FAQ says audio from its AI text-to-speech tool “can be used for commercial purposes such as advertisements, YouTube videos, and brand promotions”, as long as you follow CapCut’s terms of use and platform guidelines.
How to make a free AI voiceover in CapCut
- Go to CapCut’s Text to Speech tool and sign in.
- Paste your script and pick a language and voice.
- Adjust the speed and pitch, then preview.
- Export as MP3 or WAV, or add the voice directly to a video project in the CapCut editor.
Pros: large voice library, commercial use stated in the FAQ, fits straight into a vertical-video workflow.
Cons: CapCut’s terms and feature availability can differ by country; some advanced features may sit behind CapCut Pro.
If you’re turning the voiceover into a Short, pair it with one of the tools in our ranking of free AI video generators.
3. Google AI Studio (Gemini TTS): best for tone and emotion
Google AI Studio lets you try Gemini’s speech generation models in the browser. Google’s developer documentation lists 30 prebuilt voices (with names such as Zephyr, Puck and Kore), an extended voice library, and output as 24 kHz WAV audio. What makes Gemini TTS different is that you can steer the delivery in plain English: “Say this warmly, like a teacher explaining to a beginner”, or “Read this fast and excited, like a sports announcer”.
How to make a voiceover in Google AI Studio
- Open Google AI Studio and sign in with a Google account.
- Choose the speech generation option and a Gemini TTS model.
- Pick a voice from the list and preview it.
- Write a short style instruction, then your script.
- Run it and download the audio file.
Free tier note: at the time of writing, Google’s Gemini API pricing page lists its Flash TTS models as free of charge on the free tier, with rate limits. Google also states that content on the free tier is used to improve its products, so don’t paste private client scripts there. Check the Gemini API pricing page before you rely on it, because Google changes these limits often.
Pros: the best control over emotion and pacing, many languages, no per-minute credits to count.
Cons: the interface is built for developers; free-tier limits and model names change frequently.
4. ElevenLabs Free: the most realistic voices (personal use only)
ElevenLabs is the tool most people mean when they talk about “AI voices that sound human”. Its free plan costs $0 and includes 10,000 credits a month, along with text to speech, sound effects, voice design and three Studio projects. That is enough for several short voiceovers each month.
The catch matters if you run a business or a monetized channel. ElevenLabs’ help center says plainly: “The free plan does not include a commercial license and cannot be used for any commercial purpose.” Free-plan audio shared non-commercially must be attributed to ElevenLabs by including “elevenlabs.io” or “11.ai” in the title. ElevenLabs also says content made outside a paid subscription stays non-commercial even if you upgrade later. All paid plans include a commercial licence, starting with the Starter plan; see the ElevenLabs pricing page for current prices.
How to make a voiceover with ElevenLabs Free
- Create a free account at elevenlabs.io.
- Open Text to Speech, paste your script and choose a voice from the library.
- Adjust stability and similarity if the voice sounds too flat or too dramatic.
- Generate once, listen, then fix only the lines that need it. Each regeneration spends credits.
- Download the MP3 and add attribution to your title if you publish it.
Pros: the most natural, expressive voices of any free option; great voice library.
Cons: no commercial use on the free plan, attribution required, credits run out quickly on long scripts.
Read the licence terms yourself before publishing: see ElevenLabs’ help article on free-plan commercial use.
5. Kokoro-82M: free, open source and offline
Kokoro is an open-weight text-to-speech model with 82 million parameters. It is small enough to run on an ordinary computer, and its weights are released under the Apache 2.0 licence, which allows commercial use. Version 1.0 shipped with 8 languages and 54 voices, according to the Kokoro model page on Hugging Face.
How to use Kokoro
- Install Python, then install the Kokoro package following the instructions on the model page.
- Choose a voice ID from the voices list.
- Run the example script with your text and save the output as a WAV file.
Watch out: the model page warns that websites using the Kokoro name, such as “kokorottsai” and “kokorotts” domains, are not affiliated with the model’s author. Download it only from the official Hugging Face page.
Pros: unlimited and offline, private (your text never leaves your machine), commercial-friendly licence.
Cons: needs basic technical skills; fewer languages and less emotion than the cloud tools.
How to add the AI voiceover to your video
Once you have the audio file, the editing is the same in almost any editor:
- Lay the voice down first. Put the voiceover on the timeline before your visuals and cut the video to match the voice, not the other way round.
- Trim the silences. Remove dead air at the start and between sections. On Shorts, every half-second counts.
- Add captions. Most viewers watch muted at first. Clipchamp and CapCut can both generate captions automatically from audio.
- Keep music quiet. Set background music well below the voice so every word stays clear. If you need a track, here is how to make AI music for free.
- Export in the right shape. 9:16 vertical for Shorts, Reels and TikTok; 16:9 for regular YouTube videos.

Free AI voiceovers and the rules: what to check before you publish
- Licence: “free to use” and “free for commercial use” are different things. ElevenLabs’ free plan is the clearest example of a tool that is free but non-commercial.
- Disclosure: YouTube asks creators to disclose realistic altered or synthetic content in some cases. A standard narrator voice reading your script is usually different from making a real person appear to say something, but read YouTube’s current guidance for your situation.
- Never clone someone else’s voice without their permission. Voice-cloning features should only be used with your own voice or a voice you have rights to.
- Privacy: free cloud tiers may keep or use what you paste. Use an offline model like Kokoro for confidential scripts.
Which free AI voiceover tool should you use?
- You make videos and want everything in one place: Clipchamp.
- You post Shorts and Reels and need commercial use: CapCut.
- You want a specific mood or acting style: Google AI Studio.
- You want the most human voice for a personal project: ElevenLabs Free.
- You want unlimited, private, offline voiceovers: Kokoro.
