Smart speaker

A smart speaker is a type of loudspeaker and voice command device with an integrated virtual assistant that offers interactive actions and hands-free activation with the help of one "hot word" (or several "hot words"). Some smart speakers can also act as a smart device that utilizes Wi-Fi and other protocol standards to extend usage beyond audio playback, such as to control home automation devices. This can include, but is not limited to, features such as compatibility across a number of services and platforms, peer-to-peer connection through mesh networking, virtual assistants, and others. Each can have its own designated interface and features in-house, usually launched or controlled via application or home automation software.^[1] Some smart speakers also include a screen to show the user a visual response.

As of winter 2017, it is estimated by NPR and Edison Research that 39 million Americans (16% of the population over 18) own a smart speaker.^[2]

A smart speaker with a touchscreen is known as a smart display.^[3][4] It is a smart device that integrates conversational user interface with display screens to augment voice interaction with images and video. They are powered by one of the common voice assistants and offer controls for smart home devices, feature streaming apps, and web browsers with touch controls for selecting content. The first smart displays were introduced in 2017 by Amazon (Amazon Echo).
