⚠️ Starting January 25, 2018, the AVS Java Sample App will be put into maintenance mode. To leverage the latest Alexa features, please use the AVS Device SDK C++ Sample App, which you can find here. To discuss any specific dependencies on the AVS Java Sample App, feel free to reach out to us here. This project provides a step-by-step walkthrough to help you build a hands-free Alexa Voice Service (AVS) prototype in 60 minutes, using wake word engines from Sensory or KITT.AI. Now, in addition to pushing a button to "start listening", you can now also just say the wake word "Alexa", much like the Amazon Echo. You can find step-by-step instructions to set up the hands-free prototype on Raspberry Pi, or follow the instructions to set up the push-to-talk only prototype on Linux, Mac, or Windows.
