Speech and language-model providers
A customer's voice agent may also use speech, voice and language-model providers selected in its voice configuration. These providers process call audio, text and transcripts to run the agent. We can share the list for your deployment on request.
Location
Providers process data in the regions where they operate their services. Ask us for the regions that apply to your deployment.
