There is a voice recognition unit including a tracking unit for detecting a sound source direction and a voice segment to execute a sound source extraction process, and a voice recognition unit for inputting a sound source extraction result to execute a voice recognition process. In the tracking unit, a segment being created management unit that creates and manages a voice segment per unit of sound source sequentially detects a sound source direction, sequentially updates a voice segment estimated by connecting a detection result to a time direction, creates an extraction filter for a sound source extraction after a predetermined time is elapsed, and sequentially creates a sound source extraction result by sequentially applying the extraction filter to an input voice signal. The voice recognition unit sequentially executes the voice recognition process to a partial sound source extraction result to output a voice recognition result."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Voice segment detection for extraction of sound source","description":"There is provided an apparatus and a method for rapidly extracting a target sound from a sound signal where a variety of sounds are mixed generated from a plurality of the sound sources.
