Does Google use the text or audio I send to the Speech-to-Text API?
If you are not enrolled in the
data logging opt-in program, Google
does not use any of your content for any purpose except to provide you with
the Speech-to-Text API service. Content includes, for example, audio sent to the
API or any returned transcripts.
Will Google share the audio I send to the Speech-to-Text API?
Google does not make the audio content sent to the Speech-to-Text API
available to anyone else except as necessary to provide the Speech-to-Text API
service. For example, sometimes we might need to use a third-party vendor to
help us provide some aspect of our services, such as data storage or
transmission. In these cases, that vendor is under appropriate security and
confidentiality contractual obligations. We don't share your audio with
other parties for any other purpose.
Will the audio I send to the Speech-to-Text API, the transcription results,
or other information about the request itself, be stored on Google servers?
If so, for how long and where is the information kept, and do I have access
to it?
When you send audio to the Speech-to-Text API streaming or sync endpoints,
Google processes it in memory and does not store any customer data. Google
temporarily logs some metadata about your Speech-to-Text API requests (such as
the time the request was received and the size of the request) in order to
improve our service and combat abuse.
When you send audio to the Speech-to-Text API async endpoint, the resulting
transcript is stored for a period of approximately 5 days to give you time
to retrieve the transcript. The input audio data is not stored by the
Speech-to-Text API service. This is done strictly as a feature of the
service, to enable convenient retrieval of the data. This data is not used
by Google for any other purpose other than to deliver it to the user who
requested that it be stored.
How does Google protect and ensure the security of the data I send to the
Speech-to-Text API?
Does Google use my data to improve Speech-to-Text API services?
Google only uses data from customers who have opted in to
data logging and agreed to the relevant
terms to improve its services.
Data from customers who have not opted in to data logging is not stored or
used by Google for anything other than providing the service to the
customer.
Where is data sent to the Speech-to-Text API processed?
Data sent to Speech-to-Text is processed globally. Currently, users can
define a specific endpoint in order to limit processing of their data to
within the European Union or the United States (see the
multi-region endpoints documentation for
details). Limiting processing to a single Google Cloud region is not
currently supported.
Does Google claim ownership of the content I send in the request to the
Speech-to-Text API?
Google does not claim any ownership in any of the content (including the
audio data and returned transcript) that you transmit to the Speech-to-Text API.
Can I resell the Speech-to-Text API?
No, you are not permitted to resell the Speech-to-Text API service. You can
still integrate Speech-to-Text API into applications of independent value.
