Thanks to these mics, Alexa can listen to your voice commands even in highly crowded places. If you are using an Amazon Echo, Echo Show, or any generation of the Echo Dot model, you have far-field microphones. These far-field microphones come with the same configurations as the Far-Field Voice Development Kits do. The guard feature relies on far-field microphones built into the device to accurately capture any sounds needing verification from a human. It makes your Echo, or any other Amazon Alexa smart speaker, listen to any auditory signs that indicate an emergency. The Guard mode is a rather new upgrade to the entire Amazon Alexa line of products. If you are away and Guard Mode is turned on, you will get notified in real-time if someone breaks into your house or if your oven catches fire, triggering a smoke alarm. Guard Mode is an Alexa extension that helps you stay notified about your home security.
