Amazon Echo is designed around your voice. It's always on--just ask for information, music, news, weather, and more. Echo begins working as soon as it detects the wake word. You can pick "Alexa" or "Amazon" as your wake word. Echo is also an expertly tuned speaker that can fill any room with immersive sound. Echo uses on-device keyword spotting to detect the wake word. When Echo detects the wake word, it lights up and streams audio to the cloud, where we leverage the power of Amazon Web Services to recognize and respond to your request. Plus, Echo is Bluetooth-enabled so you can stream other popular music services like Spotify, iTunes, and Pandora from your phone or tablet.
