Smart speaker reviews These are all the posts about smart speakers on our website. A smart speaker is, as a rule, a wireless speaker with a battery and a voice assistant: most often Google Assistant or Alexa (and therefore “smart”). Of course, Siri can also be smart inside if it is an Apple product. Such devices can play music, podcasts, “communicate” with the user, answering questions, control other smart or not so smart equipment – that is, this is an important element of a smart home.
