A Professional Voice Clone (PVC) is HeyGen's highest-fidelity voice clone. Instead of a short sample, it learns your voice from 20+ minutes of your own recordings, so it captures your tone, your accent and the way you naturally speak. This guide shows you how to clone your voice with a PVC and get a great result the first time.

💡 Pro Tip: Your clone is only as good as the audio you give it. Clean, natural recordings matter more than anything else.

What do I need to create a Professional Voice Clone?

A paid HeyGen subscription plan ( Creator, Pro, Business, etc) plus the PVC add-on ($29/month or $288/year per voice)
At least 20 minutes of you speaking. 30 minutes to 2 hours gives the best results.
Up to 30 audio or video files in the app (10 through the API), 1.5 GB total, all of you and only you
File formats: MP3, WAV or M4A audio. In the app you can also upload MP4 or MOV videos and HeyGen pulls out the audio.
Clean audio: a quiet room, no music, no other voices
A good mic: an external mic, a Bluetooth mic or a modern smartphone
Recordings in one of the 11 supported languages (see the FAQ below), in the language you'll make videos in

How do I record great audio for my voice clone?

Mic

Use an external mic, a Bluetooth mic or a modern smartphone. Avoid your laptop's built-in mic.
Keep an external mic about 6 to 8 inches from your mouth, and make sure it isn't touching your clothing.
Don't set your mic too loud. If your loudest moments distort, that distortion gets baked into your clone.

Room

Record in a quiet room. Background noise makes your clone less clear and less consistent.

Delivery

Speak naturally and with energy, the way you do in your real videos.
Talk about topics you know well, like your work, your routine or a story you love to tell.
Reading a script? Vary your pace and use pauses so you don't sound flat.
Avoid slow, monotone reading, such as reading lists of words. Your clone will learn to sound flat too.

Length

Aim for 30 minutes to 2 hours. The minimum is 20 minutes.
Silence counts toward your total, so trim dead air, background noise and any spots where people talk over each other.

Which audio should I use to train my PVC?

Already have hours of yourself on video? That audio can work well, as long as it passes these checks.

Match your use case. Train on audio that sounds like the videos you'll make. Making short social videos? Use audio from your short social videos. Making training content? Use a recording of you teaching.
Keep one accent and one style. Mixing recordings with different accents or speaking styles can make the accent drift.
Include your words. Pick recordings where you say the names, brands and terms you use often, and words that show off your accent.

⚠️ Avoid:

Phone-call or video-call recordings. They make your clone sound muffled, like it's on the phone.
Music or sound effects under your voice
Other people talking, such as interviewers or audience questions
Distorted or clipped audio from a mic set too loud

How do I create my Professional Voice Clone?

In HeyGen, go to Avatar > Voices (or start from the home screen).
Click Clone your voice.
Choose Professional Voice Clone ("Our most accurate voice, trained on 20+ minutes.").
Upload your recordings and start training.

Good to know: the PVC flow is upload only, so there is no in-app recording and no consent step. Training usually takes around 15 minutes, but can occasionally take longer.

🛎️ Developers: you can create and retrain PVC voices with the API. See the Professional Voice Clone API docs. Through the API you can upload up to 10 files, capped at 1.5 GB total.

What happens after my voice finishes training?

Find your voice. It appears under Avatar > Voices > My voices with a Professional Voice Clone tag. To use it in a video, open the Avatar & Voice panel in the editor and pick it under Voice.
Adjust the speed. If your clone reads faster than you'd like, lower the speed. PVC voices have Speed, Volume, Pitch and Inflection controls.
Retrain with better audio. Not happy with the result? Delete the voice and create it again with better recordings, using the same slot. Creating it again counts as another training.
Know your training allowance. Each voice slot includes five trainings per monthly billing period, pooled across your slots. Your first training counts toward it, and so does every time you delete and recreate a voice. Failed trainings are free.

Why does my voice clone sound off? Troubleshooting

Symptom	Likely cause	Fix
Sounds muffled, like a phone call	Training audio came from a phone or video call	Re-record with a good mic and retrain
Sounds flat or monotone	Training audio was a slow, monotone read, like a list of words	Retrain on natural, energetic speech, like your real videos
Reads too fast	Your training audio is fast, long-form speech	Lower the Speed control
Accent drifts	Training audio mixes different accents or speaking styles	Retrain on recordings with one consistent accent and style
Mispronounces names	Those names aren't in your training audio	Retrain with recordings where you say them
Background noise or clicks	Noise in the room, a mic touching clothing, or a mic set too loud	Record in a quiet room, keep the mic clear of clothing, lower the input level, trim noisy parts, then retrain
