Tucked under Echo's light ring are seven microphones. These sensors use beam-forming technology to hear you from any direction, even when Echo is playing music. 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, using AWS to recognize and respond to your request.
Echo delivers crisp vocals with dynamic bass response. Its dual downward-firing speakers produce 360 degree audio to fill the room with immersive sound. Echo provides hands-free voice control for Amazon Music, Prime Music, Pandora, iHeartRadio, and TuneIn.
