Original Abstract

This paper describes the BUT Jilebi teams speech recognitionsystems created for the 2018 low resource speech recognitionchallenge for Indian languages. We investigate modifications ofmultilingual time-delay neural network (TDNN) architectureswith transfer learning and compare them to bi-directionalresidual memory networks (BRMN) and bi-directional LSTM.Our best submission based on system combination achievedword error rates of 13.92% (Tamil), 14.71% (Telugu) and14.06% (Gujarati). We present the details of submitted systemsand also the post-evaluation analysis done for lexicon discoveryusing unsupervised word segmentation.
