The first calculating unit calculates a first threshold every unit time. The second calculating unit calculates a second threshold every unit time. The first detecting unit compares first feature amount based on the input signal with the first threshold and detects the object sound period in the input signal. The second detecting unit compares second feature amount based on the input signal with the second threshold, detects the object sound period in the input signal, and outputs a detecting result. The first calculating unit calculates the first threshold based on a detecting result before unit time by the second detecting unit. The second calculating unit calculates the second threshold based on a detecting result in same unit time by the first detecting unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Object sound period detection apparatus, noise estimating apparatus and SNR estimation apparatus","description":"An object sound period detection apparatus includes a first calculating unit, a second calculating unit, a first detecting unit, and a second detecting unit.
