Creating Your Avatar and Voice
Glissez pour afficher le menu
Avatar creation in HeyGen involves recording or uploading footage of yourself to create a digital visual clone. Voice cloning, typically done with ElevenLabs and connected to HeyGen, creates a model of your voice that can read any script.
When combined, these technologies allow you to generate videos in which a digital version of you delivers content that was never physically recorded.
The default voice model in HeyGen is perfectly usable, but it is not the highest-quality option available. For more natural results, consider training a custom voice in ElevenLabs and connecting it to HeyGen through its third-party voice integration.
The improvement can be substantial, especially when it comes to accents, pronunciation, and speaking rhythm. As with any voice-cloning system, the quality of the output depends heavily on the quality of the training data. Longer recordings, clear audio, and minimal background noise generally produce a more accurate and natural-sounding voice clone.
Go to HeyGen and open the Avatars section. Click Create Avatar and choose whether to create a virtual avatar or clone yourself.
To create a clone, record a short video directly in the browser, scan the QR code to record on your phone, or upload existing footage. Better lighting and clearer footage generally produce better results. A smartphone works well for authentic content, while a high-quality camera creates a more polished look.
When generating videos, choose Avatar 4, HeyGen's highest-quality avatar model. It provides the most realistic facial movements and voice synchronization currently available on the platform.
After creating your avatar, click Add More Looks and choose Design a Look with AI. Select a style or background and let HeyGen generate alternative versions of your avatar. Treat this as a creative feature rather than a predictable workflow.
Create an account in ElevenLabs and train a voice clone using recordings of your own voice. More high-quality audio generally leads to a more accurate clone. Existing content such as course recordings, podcasts, or screencasts works particularly well.
In HeyGen's video creator, open the Voice section and select Third Party Voice → Import. Enter your ElevenLabs API key and choose your trained voice. Once imported, it can be used for all future avatar videos, with speed and volume controls available inside HeyGen.
If you prefer a simpler setup, HeyGen includes built-in voice cloning, voice enhancement tools, and a library of pre-made voices. These are often sufficient for testing and early projects.
Paste a short script into the HeyGen editor, select your avatar and voice, and generate a 720p or 1080p video. Review the result for voice quality, lip-sync accuracy, and visual artefacts.
Lip sync is usually very accurate, but hand and gesture rendering can occasionally look unnatural. Many creators avoid this issue by using tighter camera framing that keeps hands out of view.
