An Improved Single Step Non-autoregressive Transformer for Automatic Speech Recognition
Ruchao Fan, Wei Chu, Peng Chang +2
Non-autoregressive mechanisms can significantly decrease inference time for speech transformers, especially when the single step variant is applied. Previous work on CTC alignment-…
Low Resource German ASR with Untranscribed Data Spoken by Non-native Children -- INTERSPEECH 2021 Shared Task SPAPL System
Jinhan Wang, Yunzheng Zhu, Ruchao Fan +2
This paper describes the SPAPL system for the INTERSPEECH 2021 Challenge: Shared Task on Automatic Speech Recognition for Non-Native Children's Speech in German. ~ 5 hours of trans…
Fundamental Frequency Feature Normalization and Data Augmentation for Child Speech Recognition
Gary Yeung, Ruchao Fan, Abeer Alwan
Automatic speech recognition (ASR) systems for young children are needed due to the importance of age-appropriate educational technology. Because of the lack of publicly available…
Bi-APC: Bidirectional Autoregressive Predictive Coding for Unsupervised Pre-training and Its Application to Children's ASR
Ruchao Fan, Amber Afshan, Abeer Alwan
We present a bidirectional unsupervised model pre-training (UPT) method and apply it to children's automatic speech recognition (ASR). An obstacle to improving child ASR is the sca…
