MacRumors:
In an annual test comparing Google Assistant, Siri, and Alexa on smartphones, Loup Ventures’ Gene Munster found that Siri was able to correctly answer 83 percent of questions, beating Alexa but trailing behind Google Assistant.
Munster asked each digital assistant 800 questions during the test to compare how each one responded. Alexa answered 79.8 percent of questions correctly, while Google Assistant answered 92.9 percent of questions correctly.
Second place is “nice” but Siri still only answers approximately 83% of questions correctly.
