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.

Task-aware Warping Factors in Mask-based Speech Enhancement

no code implementations27 Aug 2021 Qiongqiong Wang, Kong Aik Lee, Takafumi Koshinaka, Koji Okabe, Hitoshi Yamamoto

It is easy to apply the proposed dual-warping factors approach to any mask-based SE method, and it allows a single SE system to handle multiple tasks without task-dependent training.

Xi-Vector Embedding for Speaker Recognition

no code implementations12 Aug 2021 Kong Aik Lee, Qiongqiong Wang, Takafumi Koshinaka

We present a Bayesian formulation for deep speaker embedding, wherein the xi-vector is the Bayesian counterpart of the x-vector, taking into account the uncertainty estimate.
