Abstract
A robust technique for the coding of multiband excitation (MBE) model parameters from a non-stationary speech segment is proposed in this paper. The non-stationary speech segment which has an abrupt increase in its signal energy with respect to the time is divided into 2 quasi-stationary speech segments. A variable analysis frame size technique is proposed to analyze the lower energy portion and the higher energy portion separately. A high quality fixed 1.6 kbps variable frame size MBE linear predictive (MBELP) speech coder was developed.
