Summary

Emotion influences speech and degrades ASR quality due to mismatch between input speech and acoustic model. This study proposes using DNN and CNN bottleneck features for emotional speech recognition to improve accuracy. Bottleneck features are extracted from a deep neural network with a smaller number of nodes in the middle layer, which can extract robust acoustic features. The study combines bottleneck features with other feature transformation methods, such as LDA and fMLLR, to further improve recognition accuracy. Experiments using the Kaldi toolkit and Japanese spontaneous speech corpus show that DNN and CNN bottleneck features improve recognition accuracy compared to baseline systems.
