Multi-Frequency Information Enhanced Channel Attention Module for Speaker Representation Learning

no code implementations10 Jul 2022 Mufan Sang, John H. L. Hansen

In this study, we show that GAP is a special case of a discrete cosine transform (DCT) on time-frequency domain mathematically using only the lowest frequency component in frequency decomposition.

Self-Supervised Speaker Verification with Simple Siamese Network and Self-Supervised Regularization

no code implementations8 Dec 2021 Mufan Sang, Haoqi Li, Fang Liu, Andrew O. Arnold, Li Wan

With our strong online data augmentation strategy, the proposed SSReg shows the potential of self-supervised learning without using negative pairs and it can significantly improve the performance of self-supervised speaker representation learning with a simple Siamese network architecture.
