Voice Model Estimation

(Pamornpol Jinachitra)

(to be presented later this morning)

System Diagram

• Parametric source-filter model of voice + noise
• State-space framework with derivative glottal waveform as input and A model for dynamics
• Jointly estimate AR parameters and glottal source parameters using EM algorithm with Kalman smoothing
• Reconstruct a clean voice using Kelly-Lochbaum and estimated parameters
