### AI overview

The article explains how Gradium's data residency and Zero Data Retention settings work for voice inference. It describes pinning sessions to EU or US endpoints, rejecting requests that cannot stay in the selected region, checking residency status in API responses, and disabling payload retention. It also outlines self-hosted inference options through Amazon SageMaker or on-premises deployments.

### Source excerpt

Two questions come up in almost every enterprise evaluation: where exactly does the inference run, and what do you keep? Data residency pins your Text-to-Speech, Speech-to-Text and Speech-to-Speech sessions to our EU servers, or to our US servers, enforced at the server and reported on every response, so you can assert on it instead of trusting a hostname. Zero Data Retention decides whether the text and audio processed by our servers survive the call at all.
