Command by speaking
Voice activation is a technology that allows devices to respond to spoken commands rather than physical input.
A voice-activated assistant waits for a trigger phrase before listening: Hey Siri, set a timer.
The feature appears in phones, smart speakers, cars, and home automation systems.
The lights are voice-activated.
