  3. While creating the key, turn on Restrict Key and choose which features this key can use: 11labs Text2speech Pn
    At a minimum, enable Text to Speech. Keep all other features set to “No access” unless you specifically plan to use them (e.g., Speech to Speech, Speech to Text, Sound Effects, Dubbing, etc.).

Choose a voice ID

11labs PnYou can pick any voice available to your account whether it’s stock/public voices, your own custom or cloned voices, or shared/community voices.
Tip: Add the voice to My Voices, then copy its Voice ID (for example: Bella EXAVITQu4vr4xnSDxMaL). If you want users to switch voices, store multiple Voice IDs and display them in a dropdown.
Important: Each API request uses your ElevenLabs credits. All billing happens directly with ElevenLabs, not through Base44.
