Configure ElevenLabs text-to-speech voices for use in AI Voice Call questionnaire channels. ElevenLabs provides high-quality, natural-sounding voices — including the ability to clone custom voices — that replace the default Twilio synthesis when configured.

1. Open ElevenLabs settings Navigate to Settings → ElevenLabs in the sidebar.
2. Enter your API Key Paste the API key from your ElevenLabs account (elevenlabs.io → Profile → API Keys). The key is stored encrypted.

Voice Cloning
