What is Amazon Alexa?

Amazon Alexa is a voice assistant that responds to spoken commands and questions across Amazon devices and third-party hardware. You can use it to shop for groceries, play music, control smart home devices, check weather and news, set reminders, and get answers to general questions. Alexa works through always-on microphones on Echo speakers, tablets, and compatible smart devices. Developers can build custom skills to extend Alexa's abilities, whilst consumers use it for everyday convenience through voice interaction. The service operates on a freemium model where basic voice assistant features are free with device purchase, though some shopping and premium features may have additional costs.
