Description

Speech enhancement aims at improving the intelligibility and/or overall perceptual quality of noisy speech signals. It is a key element in a wide range of applications in daily communication systems and robotics. Numerous approaches have been proposed in the literature exploiting different audio signal processing techniques. This challenging internship aims at exploiting an emerging framework based on deep neural networks (DNN), which has recently gained great success in different tasks in audio, image and language processing. Some recent studies [1,2] have shown the potential of this DNN-based approach for speech enhancement.

The intern will conduct both research and algorithm implemention while investigating the use of deep neural network for speech enhancement. Depending on obtained results, this work may lead to a patent submission and a research publication in an international conference.
