Far-field Voice Recognition
Always be heard
Tucked under Echo's light ring is an array of seven microphones. These sensors use beam-forming technology to hear you from any direction. With enhanced noise cancellation, Echo can hear you ask a question even while it's 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, where we leverage the Alexa Voice Service to recognize and respond to your request. Learn more about Echo's voice recognition.
Always Getting Smarter
Alexa—the brain behind Echo—is built in the cloud, so it is always getting smarter. The more you use Echo, the more it adapts to your speech patterns, vocabulary, and personal preferences. And because Echo is always connected, updates are delivered automatically.
...and adding new skills
We are always adding new capabilities to Echo. Recently, we’ve added streaming music from Pandora, audiobooks from Audible, Google Calendar access, live sports scores and schedules, traffic reports, Amazon.com re-ordering, control of connected devices with WeMo and Philips Hue, and more.
Advanced Audio Design
360° immersive sound
Echo has been fine-tuned to deliver crisp vocals with dynamic bass response. Its dual downward-firing speakers produce 360° omni-directional audio to fill the room with immersive sound.
..for all of your music
Echo provides hands-free voice control for Amazon Music, Prime Music, Pandora, iHeartRadio, and TuneIn. Plus, Echo is Bluetooth-enabled so you can stream other popular music services like Spotify and iTunes from your phone or tablet.
Don't lift a finger
Use Echo to switch on the lamp before getting out of bed, turn on the fan or space heater while reading in your favorite chair, or dim the lights from the couch to watch a movie—all without lifting a finger...or even raising your voice.
...to control your home
Echo works with devices such as lights and switches from Belkin WeMo and Philips Hue. Starter kits are available for easy setup. Learn more about compatible Belkin WeMo and Philips Hue connected devices.
