Back in January, Stone Temple Consulting released a virtual assistant consumer poll which revealed the majority of participants wanted the technology to provide answers instead of search results. In a follow-up to that report, the company tested the accuracy of Google Home, Microsoft Cortana, Apple Siri, and Amazon Alexa.

The study compared the results of “5,000 different questions about everyday factual knowledge” on the four virtual assistants.

Of the 5,000 questions about everyday factual knowledge, Google Home answered more questions than its rivals and it also beat out challengers for highest accuracy. The Google Assistant on Google Home answered 68.1 percent of the questions posed, with an accuracy rate of 90.6 percent. Microsoft Cortana, by comparison, answered 56.5 percent of the questions asked, with 81.9 percent accuracy. 

The Apple Siri and Amazon Alexa virtual assistants answered the fewest questions, with just 21.7 percent and 20.7 percent, respectively. Siri also demonstrated less accuracy, with 62.2 percent. But Alexa actually returned more accurate results than Cortana, with 87 percent.

Google still has the clear lead in terms of overall smarts with both Google search and the Google Assistant on Google Home. Cortana is pressing quite hard to close the gap, and has made great strides in the last three years. Alexa and Siri both face the limitation of not being able to leverage a full crawl of the web to supplement their knowledge bases. It will be interesting to see how they both address that challenge.”
