In one embodiment, a verification unit verifies a constraint condition of the filter coefficient based on whether the amount of suppression of the non-steady sound signal that would result from applying the filter to the sound signal is less than or equal to a threshold value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Voice processing device for maintaining sound quality while suppressing noise","description":"A voice processing device includes a zone detection unit which detects a voice zone including a voice signal or a non-steady sound zone including a non-steady signal other than the voice signal from a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8510108","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
