If you decide to save your audio recordings, portions of them may be reviewed to help us improve our audio recognition technologies.
For example, audio recordings can be used for Google’s audio review process. During this process, a sample of machine-selected audio snippets are disassociated from their Google accounts. Then trained reviewers can analyze the audio to annotate the recording and verify if the words said were accurately understood by Google’s audio recognition technologies. This helps a product like Google Assistant improve its ability to understand language even better in the future.
