AI Technical Summary
Existing technologies for speaker verification tasks suffer from problems such as coupling of target and non-target information, suppression of non-target information, lack of adaptive optimization mechanisms, and weak theoretical foundation, resulting in poor knowledge distillation performance.
A normalized knowledge distillation method is adopted, which decomposes the distillation loss into the knowledge distillation loss of the target speaker and non-target speaker, and introduces a learnable decoupling weight parameter γ to dynamically adjust the non-target weight. A dynamic weight update mechanism is designed to achieve decoupling and adaptive optimization between the target class and the non-target class.
Significantly reduces equal error rate (EER) and minimum detection cost function (minDCF), improving model accuracy and robustness while maintaining the same model parameter size and computational complexity.
