Abstract: Packetloss occurring in Voice-Over-IP (VoIP) is the main source of degradation in quality of experience (QoE) during a call, especially in the world when we rely heavily on video conferencing where audio is arguable more important in terms of providing a high-quality experience. This thesis surveys the different methods proposed for this problem with respect to the real-time setting using deep learning and to compare the different metrics used and their performance. We found that recurrent models remain the most popular due to their ability to model long-term relationships, while auto-encoder and GANs are also used in packet-loss concealment (PLC). These findings suggest different possible methods that could potentially help solve the problem and improve the quality of experience overall.
