Model inference sub-processors

These companies run AI models for speech recognition, language and voices. They apply only when an agency uses a model or feature that runs on them through Prosodi’s account. A model provider that an agency connects with its own API key is that agency’s own provider, under its own agreement, and is not listed here.
