TSNAT: Two-Step Non-Autoregressvie Transformer Models for Speech Recognition

1 code implementation4 Apr 2021 Zhengkun Tian, Jiangyan Yi, JianHua Tao, Ye Bai, Shuai Zhang, Zhengqi Wen, Xuefei Liu

To address these two problems, we propose a new model named the two-step non-autoregressive transformer(TSNAT), which improves the performance and accelerating the convergence of the NAR model by learning prior knowledge from a parameters-sharing AR model.

Deep Attention Fusion Feature for Speech Separation with End-to-End Post-filter Method

no code implementations17 Mar 2020 Cunhang Fan, Jian-Hua Tao, Bin Liu, Jiangyan Yi, Zhengqi Wen, Xuefei Liu

Secondly, to pay more attention to the outputs of the pre-separation stage, an attention module is applied to acquire deep attention fusion features, which are extracted by computing the similarity between the mixture and the pre-separated speech.
