CUSIDE: Chunking, Simulating Future Context and Decoding for Streaming ASR

1 code implementation31 Mar 2022 Keyu An, Huahuan Zheng, Zhijian Ou, Hongyu Xiang, Ke Ding, Guanglu Wan

The simulation module is jointly trained with the ASR model using a self-supervised loss; the ASR model is optimized with the usual ASR loss, e. g., CTC-CRF as used in our experiments.

Exploiting Single-Channel Speech for Multi-Channel End-to-End Speech Recognition: A Comparative Study

no code implementations31 Mar 2022 Keyu An, Ji Xiao, Zhijian Ou

In this paper, we systematically compare the performance of three schemes to exploit external single-channel data for multi-channel end-to-end ASR, namely back-end pre-training, data scheduling, and data simulation, under different settings such as the sizes of the single-channel data and the choices of the front-end.

An Empirical Study of Language Model Integration for Transducer based Speech Recognition

no code implementations31 Mar 2022 Huahuan Zheng, Keyu An, Zhijian Ou, Chen Huang, Ke Ding, Guanglu Wan

Based on the DR method, we propose a low-order density ratio method (LODR) by replacing the estimation with a low-order weak language model.

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

1 code implementation11 Jul 2021 Chengrui Zhu, Keyu An, Huahuan Zheng, Zhijian Ou

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 and crosslingual speech recognition methods for low-resourced languages.
