Alexa Skills are voice-activated apps that add capabilities to Alexa-enabled devices. They are available in a variety of categories, such as education, games, health, productivity, shopping, smart home, and sports. Alexa Skills are created using the Alexa Skills Kit (ASK), which is a software development framework that enables developers to create content, called skills. Users can access content in a skill by asking Alexa to invoke the skill. Alexa recognizes the speech, determines what the user wants, and then sends a request to invoke the skill that can fulfill the request. The Alexa service handles the speech recognition and natural language processing. Alexa Skills can be used to control different devices, such as lights, cameras, and other smart devices that Alexa cant control internally. There are currently more than 100,000 Alexa Skills available, and users can discover new skills by voice or in the Alexa app.
