Amazon Echo does allow you to train it for each user to better understand and distinguish the voices of all users in the house. BTW, since you have a voucher, just buy the larger Echo which is better for listening to music and have fun with it. Blueprints allows you to customize responses to questions. One simple use is to say Alexa start a timer for 5 minutes to check the grill, along with other timers while cooking. After all, it is just a parlor trick.
