I am working on speech modeling through geometrical features of speech trajectory. Usually features have been extracted from the data by treating it as a temporal signal or spectral signal. Rather than following these traditional ways of looking at the data as numbers, we are trying to understand a speech signal as a structural component. 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
-
Applications using UAVs (Unmanned Aerial Vehicles)
FUNDING PROJECTS
Risk Assessment of Moraine Dammed Glacier Lakes due to Climate Change
The application estimates mass loss and future scenarios of glacier retreat due to climate change, mainly caused by changes in temperature and precipitation.
