Definition
Wake word detection is the ability of a voice system to recognize a specific trigger word or phrase that activates it, commonly used in smart speakers and assistants. Vendors tune it for false-accept versus false-reject trade-offs, since a missed trigger loses the request and a phantom trigger starts recording unprompted.
Why it matters
Wake words matter for hands-free and embedded voice experiences, though phone-based agents typically engage on call connect instead.
