A weakly guided speaker extraction pipeline using only the initial direction, with a jointly trained tracker and spatial filter, outperforms a static-trained strongly guided baseline and resolves crossing-speaker ambiguities on synthetic data.
Target speaker extraction Let the multi-channel observation Y be modeled as additive mixture of reverberant target speech X with noise V

Steering Deep Non-Linear Spatially Selective Filters for Weakly Guided Extraction of Moving Speakers in Dynamic Scenarios
A weakly guided speaker extraction pipeline using only the initial direction, with a jointly trained tracker and spatial filter, outperforms a static-trained strongly guided baseline and resolves crossing-speaker ambiguities on synthetic data.
