Beschreibung
Acoustic multi-channel equalization techniques, which aim at inverting or reshaping the measured or estimated room impulse responses between the speech source and the microphone array, comprise an attractive approach to speech dereverberation since in theory perfect dereverberation can be achieved. However in practice, such techniques suffer from several drawbacks, such as uncontrolled perceptual effects, sensitivity to perturbations in the measured or estimated room impulse responses, and background noise amplification. The aim of this thesis is to tackle these drawbacks by designing perceptually advantageous and robust acoustic multi-channel equalization techniques for speech dereverberation as well as for joint dereverberation and noise reduction.
