On the Apple Watch, you can say "Hey Siri" to activate Siri. On Apple Watch Series 3 or later with the latest version of Apple Watch, there's a Raise to Speak feature that lets Siri respond to commands even without the Hey Siri trigger word. Just hold the watch near your mouth and speak. Siri can also be activated by holding down on the Digital Crown. On first-generation AirPods, a double tap activates Siri, and on second-generation AirPods, Siri can be activated with the "Hey Siri" command. On HomePod, say "Hey Siri" or press on the top of the HomePod to activate Siri. On Apple TV, hold down the Siri button on the remote (the button with the microphone) to activate Siri.
