Titel der Dissertation: Generative Speech Enhancement in Multimodal Applications

Reliable speech communication is often hindered by background noise, reverberation, or other signal degradations. While deep learning has advanced speech enhancement, achieving robustness and generalization remains an open challenge. This thesis investigates generative approaches to speech enhancement in both unsupervised and supervised settings. We develop probabilistic models combining Bayesian inference with deep generative networks, introduce diffusion-based methods for restoring speech under diverse distortions, and propose audio-visual frameworks for more robust speech enhancement. Finally, we benchmark these methods against predictive approaches using a new high-quality speech corpus.
The presentation will be given in English.
