摘要:

学习鲁棒的说话人嵌入是说话人日志化的关键步骤。深度神经网络可以准确地捕捉说话者的区分特征,而流行的深度嵌入(如x向量)现在是现代日记系统的基本组成部分。最近,已经提出了对用于x向量的标准TDNN架构的一些改进。例如,由于精心设计的神经模型,ECAPA-TDNN模型在说话人验证领域表现出令人印象深刻的性能。在这项工作中,我们扩展,第一次,使用ECAPA-TDNN模型的发言人日记。此外,我们通过一个强大的增强方案提高了其鲁棒性,该方案在同一批训练中连接了同一信号的几个污染版本。ECAPA-TDNN模型在近距离说话和远距离说话条件下都能提供鲁棒的说话人嵌入。流行的AMI会议语料库我们的结果表明,我们的系统显着优于最近提出的方法。

英文摘要:

Learning robust speaker embeddings is a crucial step in speaker diarization. Deep neural networks can accurately capture speaker discriminative characteristics and popular deep embeddings such as x-vectors are nowadays a fundamental component of modern diarization systems. Recently, some improvements over the standard TDNN architecture used for x-vectors have been proposed. The ECAPA-TDNN model, for instance, has shown impressive performance in the speaker verification domain, thanks to a carefully designed neural model. In this work, we extend, for the first time, the use of the ECAPA-TDNN model to speaker diarization. Moreover, we improved its robustness with a powerful augmentation scheme that concatenates several contaminated versions of the same signal within the same training batch. The ECAPA-TDNN model turned out to provide robust speaker embeddings under both close-talking and distant-talking conditions. Our results on the popular AMI meeting corpus show that our system significantly outperforms recently proposed approaches.
