A pitch emphasis apparatus obtains an output signal by executing pitch enhancement processing on each of time segments of a signal originating from an input audio signal. The pitch emphasis apparatus includes a pitch enhancing unit that carries out the following as the pitch enhancement processing: obtaining an output signal for each of times n in each of the time segments, the output signal being a signal including a signal obtained by adding (1) a signal obtained by multiplying the signal of a time further in the past than the time n by a number of samples T0 corresponding to a pitch period of the time segment for the time n, η-th power of a pitch gain σ0 of the time segment, and a predetermined constant B0, to (2) the signal of the time n, η being a value greater than 1."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pitch emphasis apparatus, method and program for the same","description":"Provided is pitch enhancement processing having little unnaturalness even in time segments for consonants, and having little unnaturalness to listeners caused by discontinuities even when time segment","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11302340","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.
