AI voice actor features
Realistic AI voice actors on demand
Type a line and the AI voice actor delivers it with natural rhythm, breaths, and emphasis instead of a flat robotic read. Every voice is built for expressive speech, so narration for explainer videos and character work in games sounds performed, not synthesised.

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

Adjust pitch, speed, tone, and emotion
Direct each read like a session with a real actor: slow the pace for a tutorial, lift 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 with no equipment needed
Open the editor, paste a script, and generate your first voiceover on the free plan with no credit card and no download. There is no microphone, audio interface, or editing suite to buy, which is why first-time users finish a clip in one 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 drives 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 L&D teams down. Generate the lesson voiceover from your script, then re-generate it in minutes when the content changes, so training audio never goes out of date.

Casting a separate actor for every character drains 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 generated.

Agency voiceover sessions take days and cost thousands per spot. Generate ad narration in the tone each campaign needs, test three reads before lunch, and localise the winner for every regional market without rebooking talent.

Recording clean narration for every upload chews up a creator's week. Generate the voice track from your script and keep the same voice across the whole channel, so every video sounds like the same host without booking sessions.

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

Re-recording a voiceover for each country multiplies cost and time. Generate the master read once, then use AI dubbing to voice it in every target market, keeping tone and pacing consistent worldwide.
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, a podcast, or a course.
Drop in a line or a full script. The editor takes typed text or a pasted document up to book length.
Browse 300+ voices across languages, accents, and styles, then preview any option within your script.
Set pitch, speed, tone and emotion line by line until the read matches the mood your script needs.
Render the voiceover in minutes, download the audio file, or send it straight into a HeyGen video.
An AI voice actor turns written text into expressive, human-sounding speech. You paste in a script, pick a voice, and the model performs it with natural rhythm and emotion, so you get finished voiceovers without hiring talent or booking a studio.
The voices are built for expressive delivery, with natural pauses, breaths, and emphasis rather than a flat read. You control pitch, pace, and emotion on each line, so a calm training narration and a high-energy ad come from the same tool and both sound performed.
Paste or type your script into the editor, choose a voice and language, then adjust tone and speed to fit the scene. Generate the audio in minutes and download it, or send it into a video, all in your browser with no plugins.
Most AI voice tools give you an audio file and that’s it. HeyGen generates the voice, then powers a talking presenter, lip-sync, and translation from the same script, so your voiceover is delivered as a finished, multilingual video instead of a clip you have to rebuild in a separate editor.
Yes. Teams generate and re-generate voiceovers in minutes instead of scheduling sessions. Advantive cut voiceover production from days to 2–3 hours and reduced content creation time by 50% after switching. See the Advantive story.
Yes. Start on the free plan and generate voiceovers with no credit card. Paid plans start at $24/month, increasing 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 keeps 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 comes from 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 work, 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 builds a reusable version of your voice. Narrate an entire series in your own voice without re-recording, or keep one consistent branded voice across every video your team makes.
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’s no mic, audio plugin, or studio setup: you type a script, pick a voice, and download the finished file. That’s 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’s best treated as a production tool, not a replacement for craft. HeyGen's voices are built with consent, and enterprise customer data is excluded from model training by default, so teams can licence and publish AI voiceovers without cutting ethical corners.
