Dr. P. Bhagath

Research

I am working in speech modeling through geometrical features of speech trajectory. Usually, features have been extracted from the data by treating it as a temporal or spectral signal. We are trying to understand a speech signal as a structural component rather than following these traditional ways of looking at the data as numbers. Apart from these problems, I am also working on the following domains:

Speech Processing
Graph signal processing
Fractal methods in speech signal analysis
Geometrical features for speech signal understanding
