Caption: Coney Island This smart speaker knows what you want to hear before you do.

• 'Audiostat', by the Canadian company Smart Speaker, is an example of a product that can make public announcements clearer for all travellers.

The brushed metal finish of the AQ Audio Smart speaker uses Apple's AirPlay technology to stream all your iTunes music wirelessly and in stereo.

An example of this is the JAMBOX, which is marketed as a "Smart Speaker" as it can also function as a speakerphone for voice calls in addition to being an audio playback device.

My judgment was that he was the smartest speaker on what I think of as the other side of the issues from myself; during the day he said a lot of things I disagreed strongly with, but interestingly enough, a few things I agreed with.
