Accessing the voice library

In HeyGen, a voice is the AI-generated speech used in your videos. Voices can be paired with avatars or used as standalone audio, giving your content tone, personality, and emotional range across a wide range of languages, accents, and speaking styles.

Voices help you align the delivery of your video with your audience and specific use case.

The voice library

All voices in HeyGen are managed through the Voice Library. This is where you can review your own voice clones, explore public AI voices, and keep everything organised in one place.

You can access the Voice Library from three primary areas:

  • AI Studio
  • The Avatars page
  • Proofread

The Voice Library includes powerful filtering tools to help you quickly find the right voice. You can filter by region, accent, age, emotion, use case, and more. You can also mark voices as favourites so your most-used options are easy to access.

Use voices in AI Studio

Within AI Studio, whenever you choose a voice for an avatar video, you have access to the complete Voice Library. From here, you can preview voices and quickly apply the one that best suits your project.

You can also create voices directly in AI Studio without creating an avatar first. In the Voice Library, select New Voice, then choose whether to clone a voice instantly, integrate a third-party voice, or generate a completely new voice using Voice Design. Once created, the voice is available across all your projects.

Manage voices from the Avatars page

Voices can also be managed from the Avatars page. By selecting an avatar and opening the voice menu, you can set a primary voice or open the Voice Library.

Setting a primary voice means that voice will automatically be used whenever you select that avatar in future videos.

Use voices in Proofread

Voices are also available in Proofread. From any script box, you can open the Track Voice tab to review all the voices used in the video. From there, you can switch between voices or create new ones while fine-tuning your script.
