These are voices obtained from an online platform or marketplace that provides access to voice models, AI-generated voices or pre-recorded voices which can be accessed by anyone.
You can either upload a voice sample to create a custom voice, or use Text‑to‑Speech synthesis to describe the voice you want in detail. Once you’re done, publish it to the marketplace to make it available to all users.

📢 Publish voice to Marketplace
Publishing your voice makes it available to other users in the Marketplace. If you prefer to keep it private, leave this off. You can remove it from the Marketplace anytime by toggling this off.
