A new report from NPD found that smart speaker sales are booming. Revenue for the market is set to increase by 50 percent for 2018-2019 in comparison to 2016-2017. Sales are likely to climb by $1.6 billion, and 19 percent of U.S. consumers said they plan to purchase one of the devices.
Developers have the ability to create audio apps, called "skills" by some manufacturers, for the devices. Amazon is the market leader with its Echo line, and Google Home devices are a strong second. Other key vendors include Apple and Samsung.
