Abstract | This paper presents a simple and effective approach to discriminate speech and music. First, the proposed modified low energy ratio is extracted from each window-level segment as the only feature. Then the system applied the Bayes MAP classifier to decide the audio class of each segment. Last, based on the fact that the audio types of neighboring segments have very strong relevance, a novel context-based post-decision method is designed to refine the classification results. The proposed method is evaluated on about 5 hours of audio data, which involves clean and noisy speech from various speakers, as well as a wide range of musical content. The experimental results are promising, and a classification accuracy of more than 97% has been achieved despite the low computation complexity of the method. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
