While the average person speaks about 15,000 words a day, increasingly they’re speaking those words to machines. Smart speaker adoption has been rapid, with voice assistants such as Alexa setting the pace. Today 53 million people in the U.S. already own at least one. The number of voice assistants in U.S. homes has doubled since 2018 (to reach 25 million) and will increase to 275 million by 2023. That amounts to 1,000% growth in only five years, according to Juniper Research.
