An Interesting Property of LPCs for Sonorant Vs Fricative Discrimination
T. V. Ananthapadmanabha, A. G. Ramakrishnan, Pradeep Balachandran
Linear prediction (LP) technique estimates an optimum all-pole filter of a given order for a frame of speech signal. The coefficients of the all-pole filter, 1/A(z) are referred to…
Detection of transitions between broad phonetic classes in a speech signal
T V Ananthapadmanabha, K V Vijay Girish, A G Ramakrishnan
Detection of transitions between broad phonetic classes in a speech signal is an important problem which has applications such as landmark detection and segmentation. The proposed…
Quadratically constrained quadratic programming for classification using particle swarms and applications
Deepak Kumar, A G Ramakrishnan
Particle swarm optimization is used in several combinatorial optimization problems. In this work, particle swarms are used to solve quadratic programming problems with quadratic co…
