Speech Enhancement (SE) is a vital technology for online human communication. Applications of Deep Neural Network (DNN) technologies in concert with traditional signal processing approaches to the task have revolutionised both the research and implementation of SE in recent years. However, the training objective of these Neural Network Speech Enhancement (NNSE) systems generally do not consider the psychoacoustic processing which occurs in the human auditory system. As a result, enhanced audio can often contain auditory artefacts which degrade the perceptual quality or intelligibility of the speech. To overcome this, systems which directly incorporate psychoacoustically motivated measures into the training objectives of NNSE systems have been proposed. A key development in speech audio processing in recent ... toggle 5 keywords
