| Abstract | The neural network method is one of the most important methods in the field of speech recognition. In this paper, we propose a new speech recognition method, probabilistic neural network (PNN) ensembles, where the Bagging ensembles method is used to form a speech recognition model with probabilistic neural networks integrated, to implement a speaker-independent English speech recognition system. This paper also demonstrates that before speech recognition, applying segment clustering algorithm to the extracted speech data, i.e., the process of time warping, can ensure the validity of dataset and the performance of PNN. Through experiments, the experimental results show that the PNN ensembles method has faster modeling speed and higher recognition rate than the single BP (Back Propagation) and the BP ensembles method, and has higher recognition rate than the traditional PNN method. |

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.
