Voice Conversion Augmentation for Speaker Recognition on Defective Datasets

no code implementations1 Apr 2024 Ruijie Tao, Zhan Shi, Yidi Jiang, Tianchi Liu, Haizhou Li

Our experimental results on three created datasets demonstrated that VCA-NN effectively mitigates these dataset problems, which provides a new direction for handling the speaker recognition problems from the data aspect.

Golden Gemini is All You Need: Finding the Sweet Spots for Speaker Verification

1 code implementation6 Dec 2023 Tianchi Liu, Kong Aik Lee, Qiongqiong Wang, Haizhou Li

We represent the stride space on a trellis diagram, and conduct a systematic study on the impact of temporal and frequency resolutions on the performance and further identify two optimal points, namely Golden Gemini, which serves as a guiding principle for designing 2D ResNet-based speaker verification models.

Scoring of Large-Margin Embeddings for Speaker Verification: Cosine or PLDA?

no code implementations8 Apr 2022 Qiongqiong Wang, Kong Aik Lee, Tianchi Liu

The emergence of large-margin softmax cross-entropy losses in training deep speaker embedding neural networks has triggered a gradual shift from parametric back-ends to a simpler cosine similarity measure for speaker verification.
