| Abstract | The paper introduces a new methodology to remove the residual effects of speech from the cepstral mean used for channel normalization. The approach is based on filtering the eigenmodes of speech that are more susceptible to convolutional distortions caused by transmission channels. The filtering of linear prediction (LP) poles and their corresponding eigenmodes for a speech segment are investigated when there is a channel mismatch for speaker identification systems. An algorithm based on pole-filtering has been developed to improve the commonly employed cepstral mean subtraction. Experiments are presented in speaker identification using speech in the TIMIT database and on the San Diego portion of the KING database. The new technique is shown to offer improved recognition accuracy under cross channel scenarios when compared to conventional methods. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
