| This paper describes the BUT Jilebi teams speech recognition
systems created for the 2018 low resource speech recognition
challenge for Indian languages. We investigate modifications of
multilingual time-delay neural network (TDNN) architectures
with transfer learning and compare them to bi-directional
residual memory networks (BRMN) and bi-directional LSTM.
Our best submission based on system combination achieved
word error rates of 13.92% (Tamil), 14.71% (Telugu) and
14.06% (Gujarati). We present the details of submitted systems
and also the post-evaluation analysis done for lexicon discovery
using unsupervised word segmentation. |
