In the Admin Center, go to Resources > Speech Providers. You can add, edit, clone, test, and delete global speech providers, and copy their reference ID.The form is the same as for project-level speech providers. For the provider settings, see Provider settings. You can store the provider credentials in a Connection.
To make a global speech provider the default for a vendor, turn on the default setting in its form.Calls in assigned projects use this credential when a flow names the vendor but no credential label. A project’s own default for that vendor takes priority. Only one global credential per vendor can be the default.
In Manage > AI & Voice Providers > Speech Providers, global speech providers appear with a Global badge. Projects can use them, for example in an endpoint.Projects can’t edit or delete global speech providers. Projects can also clone them, make them the project default, and test them.
