Speech Recognition
Definition
Keyword Spotting (KWS) is the process of continuously listening for predefined words or phrases within an audio stream. Unlike full speech recognition, KWS detects only specific keywords or wake words.
Relevance in Voice AI
Voice AI platforms use Keyword Spotting to activate voice assistants, trigger workflows, monitor compliance, detect spoken phrases, and initiate conversations without processing every spoken word.
