Wake words

Definition

Wake words are specific words or phrases that trigger a voice-activated system to start listening for further commands or input. These words serve as an activation cue for voice user interfaces, allowing devices to respond only when a user intends to interact, which enhances privacy and reduces accidental activations. Common examples of wake words include 'Alexa', 'Hey Siri', and 'OK Google'.
