Features of AI Voice Cloning
Instant or pro-grade voice clones
Pick the voice clone that fits the job. Upload a 30-second recording for an instant clone, or train a professional voice clone on a few minutes of audio for studio-grade AI voices. The same voice clone plugs into the AI voice generator for text-to-speech tasks.

Script to spoken video in one flow
Paste your script, pick a voice clone, and HeyGen turns AI voices into a finished talking video, not only an audio file. The text to video engine pairs the voice clone with an avatar, captions, and visuals. Skip the recording booth and ship fast.

Speak 175+ languages in your own voice
Clone once, speak everywhere. HeyGen's AI voice cloning pairs with AI dubbing so the same voice clone carries across 175+ languages with natural-sounding AI voices. Clone voices for podcast or YouTube content with no second voice actor, no second recording session.

Pair your clone with a lifelike avatar
Take your voice clone further with Avatar V, HeyGen's flagship avatar model. The avatar speaks in your cloned voice with full upper-body movement, multi-look generation, and long-form stability. Use the voice clone with a digital twin from a 15-second clip.

Consent-first cloning with built-in security
Every voice clone starts with explicit consent. HeyGen verifies voice ownership before training voice models, applies SOC 2 Type II and GDPR controls, and never uses your voice data to train shared AI voices. Your voice clone stays yours, with safe guardrails for client work.

Use cases
Skip the booth, the mic checks, and the retakes. Type your script, run it through a voice clone, and export a high-quality podcast voiceover in minutes. Fix a line by editing text, not by re-recording, and re-render the AI voices.
Long-form recording sessions burn weeks of studio time. Train a pro voice clone, then use the AI voices to narrate a full audiobook with consistent tone and pacing across chapters. The AI narrator keeps the voice clone steady across hours.
Reach audiences in their language without losing your voice. Clone once, run the script through HeyGen's AI video translator, and publish in Spanish, Hindi, Portuguese, and more. Attention Grabbing Media cut production from 3 days to hours this way.
Updating a lesson used to mean re-recording the whole module. Tweak the script, regenerate the voiceovers in your voice clone, and republish the same day. Course creators ship custom voiceovers in minutes instead of waiting on studio time.
Already have footage? HeyGen's AI lip sync drops your voice clone over the original mouth movements in 175+ languages. The presenter sounds like you in every market, with no reshoot and no second voice actor.
Cut voiceover delivery from days to minutes. Generate ad reads, product promos, and marketing videos using cloned voices, test multiple voice clone variations fast, and ship localized versions for every market off the same creative brief.
How it works
Clone your voice in four steps, from sample upload to finished audio or video output.
Record or upload a short, clean voice sample. Quiet room, clear speech, low background noise.
HeyGen uses AI to analyze the recording, builds a voice model, and trains your custom voice clone.
Type or paste the text you want spoken. Pick a language, pace, and emotional tone for the read.
Generate the audio or full video, preview, and download as MP4 or MP3 ready to share.




AI voice cloning is a voice cloning technology that uses artificial intelligence to clone a voice from a short clear audio sample, then trains voice models that produce AI voices on demand. The voice ai captures unique vocal characteristics so the cloned voice sounds like you.
A 30-second clear audio sample is enough for an instant voice clone. For a custom voice clone built for audiobooks, train on 1 to 3 minutes of clear audio recorded in a quiet room. Voice recording quality beats length, every time, for any voice clone.
Yes. HeyGen verifies that you own the original voice before training a voice clone, requires written consent for any third-party voice, and never uses voice data to train shared AI voices. AI voice clones tie to your account with SOC 2 Type II and GDPR coverage.
HeyGen is the best AI tool for content creators who need a voice clone inside a finished video. Other voice cloning AI stops at audio; HeyGen pairs your voice clone with an avatar, captions, and 175+ languages. The subtitle generator ships in the same flow.
Yes. Our advanced AI voice cloning carries accent, tone, and timbre into 175+ supported languages and dialects. Record one English voice sample and the same voice clone narrates Spanish, French, Hindi, Japanese, Portuguese, or any other supported language without a second recording.
AI voice cloning is legal when you clone your own voice or clone a voice you have written permission to use. Laws like the EU AI Act, the Tennessee ELVIS Act, and California publicity rights require consent before you clone someone's voice. HeyGen blocks third-party voice cloning that lacks verified permission.
Yes. HeyGen's free AI voice cloning lets you clone your voice for free and generate sample output, with limited usage on the free tier. A paid plan unlocks professional voice cloning, longer exports, full access to 175+ languages, and higher monthly credit limits.
An instant voice clone is usually ready in minutes. A professional voice clone takes longer because the algorithm processes more audio samples and voice recordings, but most users have a production-ready voice clone within an hour. Generating AI voices is near-immediate.
Yes. AI voice cloning preserves accent, dialect, and speech rhythm because those features live in your voice recordings. Clone a voice using an Irish accent and the cloned voice reads scripts with an Irish lilt. Dialects from Brazilian Portuguese to Mexican Spanish hold up well.
Yes. You can adjust speaking speed, emphasis, and emotional tone before generating AI voices, so the same voice clone reads a calm meditation, a punchy ad, or a high-energy promo. Style tags steer the read without changing the underlying AI voice.
It works, with verified results. Anton Voroniuk saves 15.5 hours per week, reaches over 1 million students, and runs production at roughly 40x lower cost using HeyGen AI voices and avatars. Full programs run on cloned voices.
Record in a quiet room with no background noise, sit close to a decent mic, and read a varied script for 1 to 3 minutes. Speak naturally at your usual pace. Clean voice recordings always beat long, noisy samples for any voice clone, no complex setup needed.
Yes. You can use a HeyGen cloned voice on TikTok, YouTube, Reels, Instagram, LinkedIn, and any social platform, as long as you own the voice or have consent. Export the voiceover in vertical 9:16 for Shorts and Reels, square for feed, or 16:9 for YouTube.
