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).
Alexa's a very capable assistant, and Amazon regularly adds new Alexa features. You can talk to Alexa. Say the wake word (which is "Alexa" by default, but you can change it), and you can ask your smart speaker to play music, control your smart home, search the internet, set a reminder or even make a call or messaging.
Update your Amazon Alexa settings to make your smart speaker a bit more secure.
