Voicebot today published our second bi-annual report on voice assistant adoption on smartphones among U.S. adults. The report includes more than 40 charts and graphs along with nearly 50 pages of analysis. The Smartphone Voice Assistant Consumer Adoption Report is based on data from a national survey conducted in October 2020. Results show that voice assistant use on smartphones rose from 51.5% in the fall of 2018 to 56.4% today.

That might seem like a modest rise. However, the population and smartphone ownership both expanded while frequency of use climbed. That lead to an 11% rise in total users and a 23% increase in daily active users of voice assistants on their smartphones.
