Title: Speech Enhancement with Deep Learning

Abstract: Deep learning (DL) based on various neural network architectures has been widely investigated for many promising applications in different fields. Recent studies on speech enhancement have resorted to deep learning as a primary tool to develop data-driven techniques. This talk introduces several new developments on speech enhancement with deep neural networks (DNN). These include a fully convolutional neural network (CNN) for complex spectrogram processing, a two-stage speech processing with DNN and Kalman filtering, and a composite neural network model using both CNN and a long short-term memory (LSTM) for complex ideal ratio mask estimation.  Experimental results demonstrate the merit of the new approaches in comparison with some state-of-the-art speech enhancement methods.
