Increase in use of smart speakers

Smart speakers are some of the most frequently purchased smart home devices and reached a sales revenue of around eight billion U.S. dollars in 2018. The most frequently purchased smart speaker brands include Amazon, Google, and Alibaba. A smart speaker is a device that can not only play music, but also provide answers from verbally introduced questions, and even control other smart home devices via a built-in virtual assistant feature.
