| Abstract | This paper presents an approach to feature enhancement error compensation for noise robust speech recognition. The conventional feature enhancement techniques estimate the enhanced clean speech from the noise corrupted speech for improving speech recognition performance under noisy environments. During speech feature enhancement process, undesired residual error is generated because of incomplete property of the noise reduction. We apply the switching linear dynamic transducer (SLDT) to compensate this residual error. The SLDT describes the sequence-to-sequence mapping in a systematic way and has been applied to stereo data based speech feature mapping for channel distorted speech recognition. We assume that feature enhancement is a channel. The proposed method shows recognition error reduction in Aurora 2 digit task and Aurora 4 large vocabulary task with the interacting multiple model. |

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.
