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.

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.

Advancing CTC-CRF Based End-to-End Speech Recognition with Wordpieces and Conformers

1 code implementation7 Jul 2021 Huahuan Zheng, Wenjie Peng, Zhijian Ou, Jinsong Zhang

Automatic speech recognition systems have been largely improved in the past few decades and current systems are mainly hybrid-based and end-to-end-based.

An empirical study of domain-agnostic semi-supervised learning via energy-based models: joint-training and pre-training

no code implementations25 Oct 2020 Yunfu Song, Huahuan Zheng, Zhijian Ou

In contrast, generative SSL methods involve unsupervised learning based on generative models by either joint-training or pre-training, and are more appealing from the perspective of being domain-agnostic, since they do not inherently require data augmentations.
