- ItemCompensation of real-world distortions in speech signals(2023) Málek, JiříThis habilitation thesis focuses on the compensation of various distortions encountered in real-world speech recordings. The thesis is organized as a collection of articles concerning this problem and published by the author between 2013 and 2022. The manuscripts were created as the output of several consecutive research projects provided by the GAČR and TAČR funding agencies. The articles follow three research topics. The main topic is the extraction of a target speaker from a mixture of several sound sources. The other topic is robust automatic speech recognition. The transcription can be complicated by unwanted sounds in the speech recording or an insufficient amount of suitable training data. Finally, the compensation of nonlinear distortions in acoustic echo cancellation is addressed.
