Voice Mirroring gives you full creative control over how your avatar sounds by letting it perform using your own vocal delivery. Instead of relying on standard text-to-speech, you record your own audio, your natural tone, rhythm, and pacing, HeyGen mirrors it through your selected avatar and voice. The result feels authentic, expressive, and true to your style.
To use Voice Mirroring, open or create a scene in Studio, choose your avatar, and go to the Audio panel. You can record directly in HeyGen or upload an existing voice file. Once Voice Mirroring is enabled, HeyGen automatically transcribes your audio, places it in the script panel, and applies your delivery to the avatar’s performance.
If you start with a text-based script and decide the tone feels off, you can easily switch the scene into Voice Mirroring mode. The script will appear as a teleprompter so you can re-record while maintaining pacing and timing. Your avatar instantly reproduces your voice pattern, intonation, emphasis, creating a delivery that feels natural and human.
Voice Mirroring works across most HeyGen voice types, including custom voice clones and imported ElevenLabs voices. It’s especially effective for creators who want to preserve their personal tone while using avatars to deliver the message. For the best results, keep your recordings natural and relaxed, exaggerated performances can overemphasize in the mirrored output. Start with short takes, review the results, and refine as you go.
By mirroring your vocal performance, this feature bridges the gap between your real-world expression and your digital presentation, making your videos sound more authentic, dynamic, and engaging.
