Data logging

Google works continuously to improve its products, including the use of customer data from Google consumer data to refine those products in many cases. Text-to-Speech is both stateless and resourceless. This means Data Access and System Event data don't apply. As a result, Text-to-Speech is out of the scope of Client Access Licenses (CAL). Google does not log any customer Text-to-Speech text or audio data.

See the Cloud Logging documentation for more details.
