SPGM: Prioritizing Local Features for enhanced speech separation performance

1 code implementation22 Sep 2023 Jia Qi Yip, Shengkui Zhao, Yukun Ma, Chongjia Ni, Chong Zhang, Hao Wang, Trung Hieu Nguyen, Kun Zhou, Dianwen Ng, Eng Siong Chng, Bin Ma

Dual-path is a popular architecture for speech separation models (e. g. Sepformer) which splits long sequences into overlapping chunks for its intra- and inter-blocks that separately model intra-chunk local features and inter-chunk global relationships.

ACA-Net: Towards Lightweight Speaker Verification using Asymmetric Cross Attention

1 code implementation20 May 2023 Jia Qi Yip, Tuan Truong, Dianwen Ng, Chong Zhang, Yukun Ma, Trung Hieu Nguyen, Chongjia Ni, Shengkui Zhao, Eng Siong Chng, Bin Ma

In this paper, we propose ACA-Net, a lightweight, global context-aware speaker embedding extractor for Speaker Verification (SV) that improves upon existing work by using Asymmetric Cross Attention (ACA) to replace temporal pooling.

On the Effectiveness of Pinyin-Character Dual-Decoding for End-to-End Mandarin Chinese ASR

no code implementations26 Jan 2022 Zhao Yang, Dianwen Ng, Xiao Fu, Liping Han, Wei Xi, Rui Wang, Rui Jiang, Jizhong Zhao

Based on the above intuition, we first investigate types of end-to-end encoder-decoder based models in the single-input dual-output (SIDO) multi-task framework, after which a novel asynchronous decoding with fuzzy Pinyin sampling method is proposed according to the one-to-one correspondence characteristics between Pinyin and Character.

Intra-Inter Subject Self-supervised Learning for Multivariate Cardiac Signals

no code implementations18 Sep 2021 Xiang Lan, Dianwen Ng, Shenda Hong, Mengling Feng

In inter subject self-supervision, we design a set of data augmentations according to the clinical characteristics of cardiac signals and perform contrastive learning among subjects to learn distinctive representations for various types of patients.
