Google works continuously to improve its products, including the use of customer
data to refine those products where customers have opted in.
By default, Speech-to-Text does not log customer audio data or transcripts.
However, to help Speech-to-Text better suit your needs, you can opt into
the data logging program. This program allows Google
to use logged customer data to refine and improve the service quality of Speech-to-Text — and in exchange, you gain access to discounted
pricing.
Data privacy and security
When you opt into the data logging program, Google does not log customer data: Google only
uses the data sent to Speech-to-Text on the project with
data logging enabled. You can continue to use other Google Cloud projects
without data logging enabled. Google only uses the data that you send to
those projects as needed to provide the service.
You continue to maintain full ownership of all data that
you upload to a project with data logging enabled. However, Google
retains ownership of the models trained from that data. For
more details about the terms and conditions for data logging, see
the terms for opt-in for data logging.
Only a limited set of authorized Google employees and contractors have
access to customer data collected via data logging, and Google uses this
data solely to train and improve Google products and services.
Google does not use customer data or any personally identifiable
information contained in logged customer data to target products,
services, or advertising towards customers or customers' users.
