The device also includes a receiver to receive an electromagnetic signal and to output a second audio signal obtained from the electromagnetic signal. An audio pre-processor of the device processes the first audio signal using the second audio signal to reduce the contribution from the other sound in a processed audio signal. The voice-controlled device then provides the processed audio signal to a speech recognition module to determine a voice command issued by the user."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-modal audio processing for voice-controlled devices","description":"A voice-controlled device includes a microphone to receive a set of sound waves that includes speech uttered by a user and other sound, and to output a first audio signal that includes a contribution ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11997448","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.
