| Abstract | The concepts of dynamic programming and pattern matching are used in a postprocessing technique for voice pitch tracking. The dynamic programming is used to achieve a smooth pitch contour based on information in the current and previous frames. A voicing decision is made based on matching the smooth contour from the dynamic programming with a set of reference templates which are representative of voiced and unvoiced speech. Three postprocessing techniques; the dynamic programming technique, nonlinear smoothing and median smoothing are appended to three standard pitch tracking algorithms. A comparative evaluation of these postprocessing techniques is performed over a data base of 58 male and female speakers ranging from 6 to 87 years of age. It is shown that significant improvement in the performance of the pitch tracking algorithms can be obtained with the dynamic progranming postprocessing. |

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.
