Phonetic-aware speaker embedding for far-field speaker verification

no code implementations27 Nov 2023 Zezhong Jin, Youzhi Tu, Man-Wai Mak

The intuition is that phonetic information can preserve low-level acoustic dynamics with speaker information and thus partly compensate for the degradation due to noise and reverberation.

Contrastive Speaker Embedding With Sequential Disentanglement

no code implementations23 Sep 2023 Youzhi Tu, Man-Wai Mak, Jen-Tzung Chien

Contrastive speaker embedding assumes that the contrast between the positive and negative pairs of speech segments is attributed to speaker identity only.

Asymmetric Clean Segments-Guided Self-Supervised Learning for Robust Speaker Verification

no code implementations8 Sep 2023 Chong-Xin Gan, Man-Wai Mak, Weiwei Lin, Jen-Tzung Chien

Contrastive self-supervised learning (CSL) for speaker verification (SV) has drawn increasing interest recently due to its ability to exploit unlabeled data.

Self-supervised Neural Factor Analysis for Disentangling Utterance-level Speech Representations

no code implementations14 May 2023 Weiwei Lin, Chenhang He, Man-Wai Mak, Youzhi Tu

Self-supervised learning (SSL) speech models such as wav2vec and HuBERT have demonstrated state-of-the-art performance on automatic speech recognition (ASR) and proved to be extremely useful in low label-resource settings.

Cluster-Guided Unsupervised Domain Adaptation for Deep Speaker Embedding

no code implementations28 Mar 2023 Haiquan Mao, Feng Hong, Man-Wai Mak

Inspired by the self-training strategies that use an existing classifier to label the unlabeled data for retraining, we propose a cluster-guided UDA framework that labels the target domain data by clustering and combines the labeled source domain data and pseudo-labeled target domain data to train a speaker embedding network.

Speaker Representation Learning via Contrastive Loss with Maximal Speaker Separability

1 code implementation29 Oct 2022 Zhe Li, Man-Wai Mak

A great challenge in speaker representation learning using deep models is to design learning objectives that can enhance the discrimination of unseen speakers under unseen domains.

Discriminative Speaker Representation via Contrastive Learning with Class-Aware Attention in Angular Space

no code implementations29 Oct 2022 Zhe Li, Man-Wai Mak, Helen Mei-Ling Meng

The challenges in applying contrastive learning to speaker verification (SV) are that the softmax-based contrastive loss lacks discriminative power and that the hard negative pairs can easily influence learning.

Protecting Genomic Privacy by a Sequence-Similarity Based Obfuscation Method

no code implementations8 Aug 2017 Shibiao Wan, Man-Wai Mak, Sun-Yuan Kung

In the post-genomic era, large-scale personal DNA sequences are produced and collected for genetic medical diagnoses and new drug discovery, which, however, simultaneously poses serious challenges to the protection of personal genomic privacy.
