iOS Shortcut to enable any speakers by voice

As the title says, this shortcut will ask you "Which Speakers?" and you tell it whatever your speakers are called, and it'll enable them and disable the others.

Example usage:

1. Say "Hey Siri FD Speakers"
2. Siri asks you "Which Speakers?"
3. Say "Living Room, Kitchen, Basement, Garage, Office"
4. Siri turns on all of those speakers and disables all other speakers.

More info:

The shortcut works by splitting up the words you say into a list of individual words. Then it gets the list of your speaker names. Then it turns off all the speakers. Then it checks to see if a word you say exists in the name of a speaker, and if so, that speaker is turned on.

Update 6/4/21 - If you're using OwnTone instead of Forked-Daapd,the URL in this shortcut needs to be updated to use owntone.local
