The representation includes information representing the spectral parameters of P subframes (where P is an integer and P<N) and information identifying the P subframes. The representation excludes information representing the spectral parameters of the N−P subframes not included in the P subframes. Generating the representation includes selecting the P subframes by, for multiple combinations of P subframes, determining an error induced by representing the frame using the spectral parameters for the P subframes and using interpolated spectral parameter values for the N−P subframes, where the interpolated spectral parameter values are generated by interpolating using the spectral parameters for the P subframes. A combination of P subframes is selected based on the determined error for the combination of P subframes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Speech coding using time-varying interpolation","description":"Encoding a sequence of digital speech samples into a bit stream includes dividing the digital speech samples into frames including N subframes (where N is an integer greater than 1); computing model p","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11270714","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.
