In this paper, we present a comparative analysis of artificial neural networks (ANNs) and Gaussian mixture models (GMMs) for design of voice conversion system using line spectral frequencies (LSFs) as feature vectors. Both the ANN and GMM based models are explored to capture nonlinear mapping functions for modifying the vocal tract characteristics of a(More)
We propose a pitch synchronous approach to design the voice conversion system taking into account the correlation between the excitation signal and vocal tract system characteristics of speech production mechanism. The glottal closure instants (GCIs) also known as epochs are used as anchor points for analysis and synthesis of the speech signal. The Gaussian(More)

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013008702 DESCRIPTION A 50-year-old male patient reported with a chief complaint of pain and intraoral swelling on the left side of the floor of the mouth since last 3 months (figure 1). Initially, owing to poor financial(More)
A genomic interval of approximately 1-1.5 Mb centered at the MSR marker on 8p22 has emerged as a possible site for a tumor suppressor gene, based on high rates of allele loss and the presence of a homozygous deletion found in metastatic prostate cancer. The objective of this study was to prepare a bacterial contig of this interval, integrate the contig with(More)
The variation in nucleotide sequence observed in the envelope (E) gene and the prM (precursor of M protein) region of different strains of Japanese encephalitis virus (JEV) was analysed. Presence of selective forces acting on these regions was investigated by computing the relative rates of synonymous (K s) and nonsynonymous (K a) substitutions. The ratioK(More)
Salmonella are a medically important Gram-negative foodborne pathogen. Genomic diversity of Salmonella is increasingly studied but at the same time, we have limited knowledge of Salmonella phage diversity. In this study, we have isolated Salmonella phages from sewage and river water. Genomic characterization of 12 Salmonella phages was carried out using(More)
Semliki Forest, Sindbis and Chikungunya viruses were grown and radio-labeled with [3H]-amino acids in Vero cells. Analysis of virus infected cell lysates by two dimensional polyacrylamide gel electrophoresis resulted in detection of polypeptides of molecular, weights corresponding to those of E1, P62, ns60, ns70/72 for Semliki Forest virus, the C, E1, 6K,(More)
Dear Editor: Sequence analysis and comparison of the ribosomal RNA (rRNA) molecule has been used for speciation and phylogenetic studies of a wide variety of organisms (7). The rRNA molecule has species-specific variable sequences that are flanked by highly conserved sequences. This hypervariable region can be amplified by polymerase chain reaction (PCR)(More)
