Alexa is Amazon's voice-activated personal assistant. Users can interact with Alexa using a device like the Amazon Echo, and some features require an active internet connection while other features do not. Alexa has various capabilities and supports many different "skills," which are essentially apps that users can use to interact with Alexa in specific ways. A user might ask their Echo to turn on the living room lights or provide traffic information for their commute home from work, for example. Skills allow users to customize the functionality of Alexa based on their own needs and interests
Alexa skills are voice-controlled applications that integrate with the Alexa Skills Kit. Topics related to building an Alexa skill include implementing a basic app, customizing intents, and writing high quality content.
