Key Frame Mechanism For Efficient Conformer Based End-to-end Speech Recognition

1 code implementation23 Oct 2023 Peng Fan, Changhao Shan, Sining Sun, Qing Yang, Jianwei Zhang

Following the initial encoder, we introduce an intermediate CTC loss function to compute the label frame, enabling us to extract the key frames and blank frames for KFSA.

A meta learning scheme for fast accent domain expansion in Mandarin speech recognition

no code implementations23 Jul 2023 Ziwei Zhu, Changhao Shan, Bihong Zhang, Jian Yu

We combine the methods of meta learning and freeze of model parameters, which makes the recognition performance more stable in different cases and the training faster about 20%.

Attention-based End-to-End Models for Small-Footprint Keyword Spotting

3 code implementations29 Mar 2018 Changhao Shan, Junbo Zhang, Yujun Wang, Lei Xie

In this paper, we propose an attention-based end-to-end neural approach for small-footprint keyword spotting (KWS), which aims to simplify the pipelines of building a production-quality KWS system.

Attention-Based End-to-End Speech Recognition on Voice Search

no code implementations22 Jul 2017 Changhao Shan, Junbo Zhang, Yujun Wang, Lei Xie

Previous attempts have shown that applying attention-based encoder-decoder to Mandarin speech recognition was quite difficult due to the logographic orthography of Mandarin, the large vocabulary and the conditional dependency of the attention model.
