Siri — the digital personal assistant on iPads and iPhones — has been spruced up in iOS 9 to provide more detailed and relevant answers, and has a few new features. For instance, the "Hey Siri" hands-free feature that debuted in iOS 8 has been improved so that it can do a better job of recognizing your voice as it's listening to everyone within earshot all the time.
Here's how to enable this feature:
- Go to Settings > General > Siri and make sure that Siri is turned on.
- Tap the "Allow 'Hey Siri' " button (it turns green).
- Siri asks you to say “Hey Siri” three different times, then say “Hey Siri, how’s the weather today?” and finally, “Hey Siri, it’s me."
- After you've done this, tap the Done button.
Now when your iPhone is connected to a charger, preface a question with "Hey, Siri" and the personal assistant gets to work. Also, note that this works with an iPhone 6s or 6s Plus even when they're not connected to a charger thanks to the M9 motion coprocessor handling the onerous task of listening to you all the time.
iOS 9 can be downloaded free via iTunes or as an over-the-air update through the Software Update function in iOS's Settings app. To install it, you'll need to be using (at least) an iPhone 4s, iPad 2, or fifth-generation iPod touch.
