AI voice actor features
Realistic AI Voice Actors, Whenever You Need Them
Type a line and the AI voice actor delivers it with natural rhythm, breathing, and emphasis instead of a flat, robotic read. Every voice is designed for expressive speech, so narration for explainer videos and character work in games sounds truly performed, not just synthesised.

300+ voices in 175+ languages
Browse 300+ voices across different ages, accents, and delivery styles, then generate the same script in 175+ languages from a single editor. The AI voice generator assigns a different narrator for each project without the need to book a new hire, a studio session, or a recording facility.

Adjust pitch, speed, tone, and emotion
Direct each read as you would a session with a real actor: slow the pace for a tutorial, increase the energy for an ad, or shift the emotion from calm to urgent. Adjust pitch, speed, tone, and emphasis on any line until the delivery matches your script.

Start Free Without Any Equipment
Open the editor, paste a script, and generate your first voiceover on the free plan with no credit card and no download. You do not need to buy a microphone, audio interface, or editing suite, which is why most first-time users complete a clip in a single sitting.

Pair Voices with On-Screen Video
A voiceover file is only half the deliverable. Send any generated voice straight into the AI video generator and it will drive a talking presenter, so the same script becomes a finished video with a face and lip movement, not just audio.


Hiring narrators for every course update slows down L&D teams. Generate the lesson voiceover directly from your script, then re-generate it in minutes when the content changes, so your training audio never becomes outdated.

Casting a separate actor for every character can quickly exhaust an indie budget. Give each role its own AI voice actor, then use AI lip sync so the character on screen mouths the exact lines you have generated.

Agency voiceover sessions take days and can cost thousands for each spot. Generate ad narration in the tone each campaign needs, test three versions before lunch, and localise the winning one for every regional market without having to rebook talent.

Recording clean narration for every upload can take up most of a creator’s week. Generate the voice track directly from your script and keep the same voice across the entire channel, so every video sounds like it has the same host, without needing to book recording sessions.

Booking a booth to record an entire book is slow and expensive. Convert chapters or show scripts into steady, natural narration, and keep one consistent voice across every episode so your series sounds like it has a single host.

Re-recording a voiceover for each country increases cost and time many times over. Record the master read once, then use AI dubbing to voice it for every target market, while keeping tone and pacing consistent across the globe.
How the AI voice actor works
Go from script to finished voiceover in four steps, entirely in your browser, and reuse the audio in a video, podcast, or course.
Type a line or paste your full script. The editor accepts typed text or a pasted document, even up to book length.
Browse 300+ voices across languages, accents, and styles, then preview any option within your script.
Adjust pitch, speed, tone, and emotion line by line until the read matches the mood your script requires.
Render the voiceover in minutes, download the audio file, or send it directly into a HeyGen video.
An AI voice actor converts written text into expressive, natural-sounding speech. You paste a script, choose a voice, and the model delivers it with natural rhythm and emotion, so you get ready-to-use voiceovers without hiring voice talent or booking a studio.
The voices are designed for expressive delivery, with natural pauses, breaths, and emphasis rather than a flat read. You can control pitch, pace, and emotion on each line, so a calm training narration and a high-energy advertisement come from the same tool and both sound professionally performed.
Paste or type your script into the editor, choose a voice and language, then adjust the tone and speed to suit the scene. Generate the audio in minutes and download it, or send it into a video, all within your browser with no plug-ins.
Most AI voice tools simply give you an audio file and stop there. HeyGen not only generates the voice, but also powers a talking presenter, lip-sync, and translation from the same script, so your voiceover is delivered as a complete, multilingual video instead of just an audio clip that you have to rework in a separate editor.
Yes. Teams generate and re-generate voiceovers in minutes instead of scheduling sessions. Advantive cut voice-over production from days to 2–3 hours and reduced content creation time by 50% after switching. Read the Advantive story.
Yes. Start on the free plan and generate voiceovers without a credit card. Paid plans start at $24/month, increasing your limits on length and downloads, unlocking more voices and languages, and adding commercial usage rights for client and business projects.
Yes. The same script can be voiced in 175+ languages and a range of regional accents. Pick a native-sounding voice for each market, or generate one read and localise it, so global content maintains a consistent style without separate recording sessions.
Yes. Assign each character their own voice, then adjust pitch, age, and emotion to keep them distinct. Animate the character to speak on screen with Avatar IV, so a full cast can be created by one editor instead of multiple hires.
Yes, on paid plans the voiceovers are cleared for commercial use, so you can publish them in ads, client projects, courses, and monetised videos. The voices are consent-based, which keeps brand and marketing content on safe legal footing.
Yes. Record a short sample and AI voice cloning will create a reusable version of your voice. Narrate an entire series in your own voice without recording again, or maintain one consistent branded voice across every video your team produces.
Yes. Pair any voiceover with an on-screen presenter so the words are spoken, not just heard. HeyGen animates a photo or character to match the audio, turning a voice track into a finished talking-head video from the same script.
No. Everything runs in your browser with simple controls. There is no mic, audio plugin, or studio setup: you type a script, choose a voice, and download the finished file. That is what makes it practical for people who have never edited audio.
Yes. Upload a rough take and speech cleanup removes filler words, pauses, and false starts, then rebuilds the frames between cuts so the result plays as one continuous take instead of a jumpy edit.
It is best used as a production tool, not as a replacement for creative craft. HeyGen's voices are built with consent, and enterprise customer data is excluded from model training by default, so teams can license and publish AI voiceovers without compromising on ethics.
