Speech Enhancement and Robust Speech Recognition


Problem Statement

In the past decades, significant advances have been achieved in the area of automatic speech recognition (ASR). However, the performances of the speech processing systems degrade rapidly when they are used in adverse environments. The noisy speech can be modeled as following.


The goal of this project is to design an effective signal processing algorithm to effectively remove the ambient noises such as the computer noise in an office, the wind noise and engine noise inside a car et al. The noise signal can be either stationary or quasi-stationary.   Back
