Voice search is no longer a novelty. Increasingly, people are using personal assistants like Siri and Google Assistant to ask questions and perform basic searches. In May of 2016, approximately 20 percent of all searches performed on Google's mobile app and Android devices were done by voice. The popularity of products like Amazon Echo and Google Home will only increase consumers' comfort with voice search. Research by ComScore suggests that 50 percent of searches will be voice-based by 2020.
