摘要:

多分支卷积神经网络结构在说话人确认中得到了广泛的关注,因为多个并行分支的聚合可以显著提高性能。然而,由于模型参数的增加和额外的操作,这种设计在推理时间内不够有效。在本文中,我们提出了一个新的多分支网络架构RepSPKNet,使用重新参数化技术。通过这种技术,我们的骨干模型包含一个有效的VGG类推理状态,而其训练状态是一个复杂的多分支结构。我们首先将RepVGG的具体结构引入到说话人确认中,并提出了这种结构的几种变体。在基于VoxCeleb的测试集上评估性能。我们证明了分支多样性和分支容量在RepSPKNet设计中起着重要作用。我们的RepSPKNet在VoxCeleb 1-H上实现了1.5982%的EER和0.1374 minDCF的最新性能。

英文摘要:

Multi-branch convolutional neural network architecture has raised lots of attention in speaker verification since the aggregation of multiple parallel branches can significantly improve performance. However, this design is not efficient enough during the inference time due to the increase of model parameters and extra operations. In this paper, we present a new multi-branch network architecture RepSPKNet that uses a re-parameterization technique. With this technique, our backbone model contains an efficient VGG-like inference state while its training state is a complicated multi-branch structure. We first introduce the specific structure of RepVGG into speaker verification and propose several variants of this structure. The performance is evaluated on VoxCeleb-based test sets. We demonstrate that both the branch diversity and the branch capacity play important roles in RepSPKNet designing. Our RepSPKNet achieves state-of-the-art performance with a 1.5982% EER and a 0.1374 minDCF on VoxCeleb1-H.
