In one embodiment, a spectrum detector identifies dominant spectrum energy frequency by detecting the dominant spectrum energy band present in spectrum of sound energy. A modified mel filter bank is designed by revising spectral positioning of the first mel filter bank and the second mel filter bank according to the identified dominant frequency. A feature extractor extracts the features from first mel filter bank, second mel filter bank and the modified mel filter bank which are further classified in order to detect the sound of interest."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Modified mel filter bank structure using spectral characteristics for sound analysis","description":"A system and method for detection of sound of interest amongst plurality of other dynamically varying sounds is disclosed.
