Integrate Alexa directly into your connected product. The AVS Device SDK provides C++-based libraries that enable your device to process audio inputs and triggers, establish persistent connections with AVS, and handle all Alexa interactions. The included capability agents expose the AVS API to handle core Alexa functionality, including speech recognition and synthesis, and other capabilities such as streaming media, timers and alarms, notifications, weather reports, and thousands of custom skills. Additionally, the SDK provides the hooks required to add your own wake word engine and audio player.
