Alexa and the All-new Echo (4th Gen) come with multiple layers of personal privacy built in so that users can feel secure. All Echo smart speakers come with the microphone off buttons allowing users to delete all voice recordings at any time. Special ultrasound sensors allow the All-new Echo (4th Gen) to automatically react when someone walks into the room, whether that be adjusting the lights, playing their favorite song, or turning on the latest episode of The Rings of Power.
