Implement AVS Infrastructure

Learn how to implement the infrastructure required to enable the Alexa Voice Service (AVS) on your device.


To access AVS, your device must obtain a Login with Amazon (LWA) access token. The device includes this token with each request to AVS to authorize the Amazon account for the device user. Learn about your options for obtaining an LWA token to authorize your device users.

Wake Word Verification

Cloud-based wake word verification improves wake word accuracy for devices that implement AVS by reducing false device wakes caused by utterances that sound similar to the wake word. For example, words that might cause a false wake for "Alexa" include "Alex", "election", and "Alexis."
