You control Sonos speakers with a built-in voice assistant using your voice. This allows you to easily switch to the next song or ask Alexa to start a Spotify playlist. You can also manage your daily tasks using your voice and a Sonos speaker with a built-in voice assistant. Update your calendar, create a shopping list, or ask for the latest news. Other smart devices also work with the voice assistant. For instance, you can switch your smart lighting on and off or ask the coffee machine for an espresso while you're still in bed.
