| Abstract | When developing a speech recognition system, one must start by deciding what the units to be recognized should be. This is for the most part a straightforward choice in the case of word-based languages such as English, but becomes an issue even in handling languages with a complex compounding system like German; with an agglutinative language like Japanese, which provides no spaces in written text, the choice is not at all obvious. Once an appropriate unit has been determined, the problem of consistently segmenting transcriptions of training data must be addressed. This paper describes a method for learning a lexicon from a training corpus which contains no word-level segmentation, applied to the problem of building a Japanese speech recognition system. We show not only that one can satisfactorily segment transcribed training data automatically, avoiding human error, but also that our system, when trained with the automatically segmented corpus, showed a significant improvement in recognition performance. |

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.
