| Abstract | Pitch determination algorithm is a critical part in speech coding algorithm. However, in telephone quality speech, the fundamental frequency is often weak, or even missing, which affects the performance of the pitch determination algorithms significantly. Thus in this paper, a robust time-domain pitch determination algorithm is proposed to specifically tackle this problem. It restores the weak or missing fundamental frequency by applying a nonlinear process to the original speech, and calculate a combined autocorrelation function (ACF) based on both the original speech and the nonlinearly processed speech. Furthermore, considering the particular properties of telephone quality speech, a Pitch Candidate Refinement Function (PCRF) that incorporates a newly introduced parameter Long-Time Average Pitch (LTAP) is used to refine the combined ACF. Finally the pitch candidates are selected based on the combined ACF and a dynamic programming is utilized to track down to the true pitch. Experiments results on Keele pitch database show that the proposed algorithm can reduce the gross pitch error rate of telephone speech by about 3% compared to a traditional ACF pitch determination 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.
