Julie wants to get an Echo, but her husband is worried about privacy and eavesdropping. Are they safe? Leo says it's about as safe as a smartphone. Anything that has a microphone that's connected or broadcasts with a radio can be listened to quite easily. Alexa is always listening, that's true, but it's only listening for the wake word "Alexa," and then whatever follows that for up to 2 minutes. It won't widen the scope until the magic word is uttered. Then it sends the request to the home office for an answer. Can it incidentally record?
