Exploiting Single-Channel Speech For Multi-channel End-to-end Speech Recognition

Keyu An, Zhijian Ou

Recently, the end-to-end training approach for neural beamformer-supported multi-channel ASR has shown its effectiveness in multi-channel speech recognition. However, the integrati…

Multilingual and crosslingual speech recognition using phonological-vector based phone embeddings

Chengrui Zhu, Keyu An, Huahuan Zheng +1

The use of phonological features (PFs) potentially allows language-specific phones to remain linked in training, which is highly desirable for information sharing for multilingual…

Deformable TDNN with adaptive receptive fields for speech recognition

Keyu An, Yi Zhang, Zhijian Ou

Time Delay Neural Networks (TDNNs) are widely used in both DNN-HMM based hybrid speech recognition systems and recent end-to-end systems. Nevertheless, the receptive fields of TDNN…

CAT: A CTC-CRF based ASR Toolkit Bridging the Hybrid and the End-to-end Approaches towards Data Efficiency and Low Latency

Keyu An, Hongyu Xiang, Zhijian Ou

In this paper, we present a new open source toolkit for speech recognition, named CAT (CTC-CRF based ASR Toolkit). CAT inherits the data-efficiency of the hybrid approach and the s…
