AI总结:
本文利用ASR预训练Conformer,通过迁移学习、知识蒸馏和轻量级适配器三种策略,在VoxCeleb上实现低至0.43%的EER,有效迁移ASR能力至说话人验证。
摘要:
本文探讨了将ASR预训练的Conformer用于说话人验证,利用其在语音信号建模方面的优势。我们提出了三种策略:(1)迁移学习初始化说话人嵌入网络,提高泛化能力并减少过拟合。(2)知识蒸馏训练更灵活的说话人验证模型,将帧级ASR损失作为辅助任务纳入其中。(3)轻量级说话人适配器,在不改变原始ASR Conformer的情况下实现高效特征转换,允许ASR和说话人验证并行进行。在VoxCeleb上的实验显示了显著改进:迁移学习实现了0.48%的等错误率(EER),知识蒸馏实现了0.43%的EER,而说话人适配器方法仅向130.94M参数的模型添加了4.92M参数,达到了0.57%的EER。总体而言,我们的方法有效地将ASR能力迁移到说话人验证任务中。
英文摘要:
This paper explores the use of ASR-pretrained Conformers for speaker verification, leveraging their strengths in modeling speech signals. We introduce three strategies: (1) Transfer learning to initialize the speaker embedding network, improving generalization and reducing overfitting. (2) Knowledge distillation to train a more flexible speaker verification model, incorporating frame-level ASR loss as an auxiliary task. (3) A lightweight speaker adaptor for efficient feature conversion without altering the original ASR Conformer, allowing parallel ASR and speaker verification. Experiments on VoxCeleb show significant improvements: transfer learning yields a 0.48% EER, knowledge distillation results in a 0.43% EER, and the speaker adaptor approach, with just an added 4.92M parameters to a 130.94M-parameter model, achieves a 0.57% EER. Overall, our methods effectively transfer ASR capabilities to speaker verification tasks.
