HeyGen lets you connect external voice providers like ElevenLabs or LMNT so you can use their voices directly in your HeyGen projects. You can integrate these voices from three different areas of the platform: AI Studio, Avatar Settings, and the Proofreading Tool.
Below is the updated, streamlined guide.
1. Integrate Third-Party Voices in AI Studio

Choose your avatar.
Hover over the Scene icon (person icon).
Under Voice, click the dropdown bar.
In the Voice settings panel, click Voice → + New Voice.
Select Integrate 3rd Party Voice → Import Voice.
Choose your provider (ElevenLabs or LMNT).
Paste your API key into Paste your API key here.
Click Confirm.
Your imported voices are now available to use in AI Studio.
2. Assign a Third-Party Voices to your Avatar slot.
Hover over the avatar Group slot.
Click the three dots (…).
Hover over Set Primary Voice → click Manage Voices.
Click + New Voice.
Select Integrate 3rd Party Voice → Import Voice.
Choose ElevenLabs or LMNT.
Paste your API key → Confirm.
Your integrated voices will now appear in your voice list.
3. Integrate Third-Party Voices in the Proofreading Tool
Open your Proofread file.
Click the Track Box next to the Speaker box.
Example: “Track 1: Clone from segment:”Click Select Track Voices → + New Voice.

Choose your provider (ElevenLabs or LMNT).

Your voices can now be selected inside the proofreader.
🛎️ Note: If you run out of ElevenLabs or other third-party credits, your integrated voices won’t work in HeyGen. To avoid interruptions, make sure you have enough credits in your third-party account to keep everything running smoothly.
Trouble integrating?
If you’re getting an Invalid API key error when integrating ElevenLabs, please make sure to enable the necessary permissions, such as:
Text to Speech
Voices
Voice Generation
Models
History
User
You can do so by going to ElevenLabs and navigating to your ElevenLabs API Settings, and then clicking edit (pencil icon) to open up the permissions model, and then giving full access to the permissions listed above.
Alternatively, you can also turn off Restrict Key to grant full access. This should resolve the “Invalid API key” error. If none of that works, please roll a new API key, set the right permissions, and try again.
