Alexa is optional and Facebook has their own voice recognition for Portal features, You can use the wake word “Hey Portal” for a limited set of portal commands mostly around calling and messaging, or “Alexa” for all the Alexa capabilities. When using Alexa functionality Facebook isn’t suppose to “listen” at all. (Though not sure if these queries still flow through their servers or not?) https://portal.facebook.com/help/2149102838698668/ https://portal.facebook.com/help/2149102838698668/
