It’s creepy and true; Amazon is listening.
Millions of people have the company's smart speakers in their homes and Amazon employs thousands of workers in different countries around the world to analyze snippets of audio picked up by the devices. The goal is to help improve the software's understanding of language to better answer user requests.
While it’s true that technically Amazon listens, the employees are required to sign non-disclosure agreements about what they hear, and Amazon says only a small fraction of audio is listened to and analyzed.
If you don’t want to be in the mix of what is listened to, you can opt out of having your voice recording used in development of new features in the software's privacy settings. In case you’re wondering, there are even protocols in place for when possible crimes are heard.
