Research interests

My research interests focus on speech analysis of pathological voices and speech modifications for intelligibility enhancement. Adaptive sinusoidal models are mostly used for analysis and modifications.

Thesis

• PhD thesis: Intelligibility Enhancement of Casual Speech based on Clear Speech Properties
• Master thesis: Voice tremor detection using Adaptive Quasi-Harmonic Model
