Annual Smart Speaker IQ Test (2 minute read)
These guys tested four smart speakers, Alexa, Siri, Google Assistant, and Cortana, with 800 questions each. Google Asssistant won with 88% of questions correctly answered vs. Siri at 75%, Alexa at 73%, and Cortana at 63%. The questions were in 5 categories: local, commerce, navigation, information, and command. Google Assistant was the best at every one except for commands (where Siri was the best). Siri and Google were head and shoulders above the rest in Local and Navigation in particular, due to their proprietary maps data. Siri has greatly improved over the past year, where it answered only 52% of questions correctly.
