An audio signal is received by receiver circuitry. A pitch analysis is performed on the received audio signal by pitch analysis circuitry. A higher-order statistics analysis is performed on the audio signal by statistics analysis circuitry. Logic circuitry determines, based on the pitch analysis and the higher-order statistics analysis, whether the audio signal includes a voice region. The logic circuitry outputs a signal indicating that the audio signal includes voice if the audio signal was determined to include a voice region or indicating that the audio signal does not include voice if the audio signal was determined not to include a voice region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting voice regions in a non-stationary noisy environment","description":"Methods, devices, and systems for voice activity detection.
