| Abstract | For GMM-UBM based text-independent speaker recognition, the performance decreases significantly when the test speech is too short. Considering that the use of text information is helpful, a K-phoneme-class scoring based multiple phoneme class speaker model method (shortened as K-phoneme-class based multi-model method, abbreviated as KPCMMM) is proposed including a phoneme class speech recognition stage and a phoneme class dependent multi-model speaker recognition stage, where K means the number of most likely phoneme classes to be used in the second stage. Two different phoneme class definitions, expert-knowledge based and data-driven, are compared, and the performance as a function of K is also studied. Experimental results show that the data-driven phoneme class definition outperforms the expert-knowledge based one, and that an appropriate K value can lead to much better performance. Compared with the baseline GMM-UBM system, the proposed KPCMMM can achieve a relative equal error rate (EER) reduction of 38.60% for text-independent speaker recognition with a length of less than 2 seconds of test speech. |

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.
