Important Notes for ElevenLabs

When using ElevenLabs with BYOK:

Voice Library Only - You only have access to voices in your ElevenLabs Voice Library

No Public Voices - You don't automatically get access to all public ElevenLabs voices

Add Voices First - Before using a voice, add it to your library at https://elevenlabs.io/app/voice-library

Voice IDs - Use the voice ID from your ElevenLabs dashboard

Removing BYOK Configuration

To remove a provider and go back to HMS Sovereign's default keys:

Security

API keys are stored securely and encrypted at rest

Keys are never exposed in API responses

Only encrypted references are stored in your account

You can rotate keys at any time by adding a new key for the same provider
