With the Apple Watch, you can do a lot with your voice. Siri is an integral part. It makes interaction with the watch faster and is easy to use.
There are a couple of ways to start using Siri. You can either press and hold the digital crown or you can raise your wrist, and when the Apple Watch turns on, simply say “Hey Siri.”
Some of the great ways to use Siri including dictating a message reply, mapping out directions, launching apps, and checking the score of your favourite sports team. Sadly you’ll have to use handoff if you ask Siri something that requires an internet search.
I’ve also found using “Hey Siri” to be a little hit or miss at times. You do need to make sure your Apple Watch turns on, but there are times where Siri just won’t respond.
