Close up of a Smart Speaker System

Caption

With this smart speaker skill, the device plays white noise and records how the noise is reflected back to detect breathing motions of infants' tiny chests. It can track both small motions -- such as the chest movement involved in breathing -- and large motions -- such as babies moving around in their cribs. It can also pick up the sound of a baby crying.
