A daily discourse, in the middle of winter:
Alexa, what's the heat set to?
- Sorry, what device?
Kitchen
- That's not supported yet
Alexa, what's the temperature set to?
- The heat's set to twenty
Alexa, set the heat to nineteen
- Sorry, what device?
Kitchen
- It's set to heat
Alexa, set the temperature to nineteen
- The heat's set to nineteen
I'll call it natural-language when I don't have to remember which synonym turns up the heat.
