Voice assistants, smart speakers, and all manner of voice-first technology have enjoyed remarkable growth and adoption. Voicebot.AI reports that the smart speaker install base within the U.S. grew 40% from 2018 to 2019, now exceeding 66 million units. International markets have grown even more dramatically — Dutch adoption of smart speakers exploded from 0% to 5% in just four and a half months, for example, with no sign of slowing down.
