Low-resource speech recognition has been long-suffering from insufficient training data. In this paper, we propose an approach that leverages neighboring languages to improve low-resource scenario performance, founded on the hypothesis that similar linguistic units in neighboring languages exhibit c…
Speech emotion recognition (SER) is a challenging task whose performance heavily relies on suitable affect-salient representations. Recently, transformer has exhibited outstanding qualities in learning relevant representations associated with this task. However, a normal transformer is only able to…
Discriminative nonnegative matrix factorization (DNMF) has been investigated as a promising basis-learning method for monaural source separation. To the best of our knowledge, however, no good and sound discussion has been made on quantitative definition of discriminability and it is difficult to ev…
When building a language model (LM) for spontaneous speech, the ideal situation is to have a large amount of spoken, in-domain training data. Having such abundant data, however, is not realistic. We address this problem by generating texts in spoken language from those in written language by using a…
In this paper, we propose a method to estimate statistical divergence between probability distributions by a DNN-based discriminative approach and its use for language identification tasks. Since statistical divergence is generally defined as a functional of two probability density functions, these…
