If you have an Android, you'll use Google Now. Id you have an iPhone, you’ll use Siri. And if you have a Windows Phone, you’ll use the recently released Cortana. They’re all programmed to answer your questions as quickly and helpfully as possible, but which one of them is the best?
Smartphones from Google, Apple, and Microsoft all offer these personal assistants who claimed to be flush with knowledge drawn from around the web. But when it comes to providing useful answers, only one has the capability, only one is the clear winner and can stump the other two any time of the day.
According to a study by the firm Stone Temple Consulting, each of the three voice apps were tested with 3,086 real-world questions structured to decide which voice app gave the best responses. The winner by a sizeable margin was Google Now.
"All queries in this test were done using voice commands, even when using Google and Bing. The reason we did this is that there are many commands in Google and Bing that behave differently when the search query is typed in, and we wanted to do a straight apples to apples comparison." Eric Enge of Stone Temple explained.
Stone Temple presented each service with 3000 voice queries — What is a group of monkeys called? Who invented Facebook? — and tabulated the results.
Not surprisingly, given Google's specialty in search, Google Now was the clear leader. It returned the most enhanced results and complete answer by a wide margin. The study cross-checked the queries with web searches on Bing and Google. Interestingly, Bing returned more complete results than Cortana, indicating that Microsoft could improve its mobile assistant by more fully integrating it with its search engine.
The study also checked a bunch of Easter eggs — What does the fox say? What is love? — but it doesn't provide any concrete data on which system has the best sense of humor.
