In particular, we demonstrate that an unsupervised spatial clustering algorithm is sufficient to guide the training of a deep clustering system. We argue that previous work on deep clustering requires strong supervision and elaborate on why this is a limitation. We demonstrate that (a) the single-channel deep clustering system trained according to the proposed scheme alone is able to achieve a similar performance as the multi-channel teacher in terms of word error rates and (b) initializing the spatial clustering approach with the deep clustering result yields a relative word error rate reduction of 26% over the unsupervised teacher. https://ris.uni-paderborn.de/download/12874/12925/ICASSP_2019_Drude_Paper.pdf application/pdfno 2019 eng ICASSP 2019, Brighton, UK Drude, L., Hasenklever, D., & Haeb-Umbach, R.
