End-To-End Optimization of Online Neural Network-supported Two-Stage Dereverberation for Hearing Devices. (arXiv:2204.02978v1 [eess.AS])
cs.LG updates on arXiv.org arxiv.org
A two-stage online dereverberation algorithm for hearing devices is presented
in this paper. The approach combines a multi-channel multi-frame linear
filtering approach with a single-channel single-frame post-filter. Both
components rely on power spectral density (PSD) estimates provided by deep
neural networks (DNNs). This contribution extends our prior work, which shows
that directly optimizing for a criterion at the output of the multi-channel
linear filtering stage results in a more efficient dereverberation, as compared
to placing the criterion at the output …
