Siri Knowledge uses a combination of web searches, inbuilt apps, and Wolfram Alpha to find the answers to a fantastic variety of questions.
When asked a question, rather than return a list of search results in Google, Siri reads out and displays the answer in a notification.
The results can be a little hit and miss, but for the most part are surprisingly accurate, especially when it comes to mathematics and general knowledge.
In this article, we trigger Siri using the “Hey Siri” voice command. Did you know there are other methods available, depending on your device? You can read about them all in our how to use Siri guide.
Here are some examples of the kind of questions you can ask:
Hey Siri, who is the Prime Minister of Australia?
Hey Siri, when was the Brooklyn Bridge built?
Hey Siri, how do you spell Brooklyn Bridge?
If Siri knows the answer (or thinks it knows the answer), it will be displayed on the screen along with voice feedback.
If the search doesn’t return definitive results, Siri will offer a list of links and topics it considers to be relevant to your query.
