| Abstract | In this paper, Kalman and Least Mean Square based filters are used for colored noise corrupted speech enhancement. Unlike previous studies a second speech signal has been utilized as colored noise which represents the situation where two persons are talking concurrently. Such a setup will help analyse the performance of speech enhancement algorithms when there are more than one speech components in the signal to be analysed and main speech signal has to be recovered. Final Prediction Error method has been employed for determining the model parameters, Speech was modeled with AR model and selected methods has been tested for their performance in terms of mean square error. The experimental results show that dual Kalman filter, which estimates both state and parameters concurently, has produced lower mean square error values when compared to joint and single Kalman filters. Joint Kalman filter, on the other hand, produced lower mean square error than single Kalman filter. Finally, it was observed that, the performance of LMS based filters was not adequate for the enhancement of colored noise corrupted 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.
