AVS provides programming interfaces to access the cloud-based service from your product, regardless of its operating system. Each interface contains logically grouped messages called directives and events that enable your device and the AVS cloud to communicate directly. The APIs handle core Alexa functionality, including speech recognition and synthesis, and other capabilities such as streaming music, timers and alarms, notifications, weather reports, and skills—enabling your device to capture an utterance, process it in the cloud, and playback an intelligent speech response.
