How do Echo Devices Recognize the Wake Word?
Echo devices are designed to detect only your chosen wake word (Amazon, Alexa, Computer, or Echo). The device detects wake word by identifying acoustic patterns that match the wake word. Once the word is detected, audio begins streaming to the cloud, including a fraction of a second of audio before the wake word. No audio is stored or sent to the cloud unless the device detects the wake word (or Alexa is activated by pressing a button).
How do I know when Echo devices are streaming audio to the cloud?
When Echo devices detect wake word to activate Alexa, a visual indicator appears on the device to indicate that the device is recording your request to stream to the cloud. For more information visit our website.
