摘要翻译：
我们研究了深度神经网络在文本无关说话人识别任务中的性能。我们证明了在分类神经网络的最后一个分类层使用角softmax激活代替简单的softmax激活可以训练一个更广义的鉴别说话人嵌入提取器。余弦相似度是该嵌入空间中说话人验证的有效度量。我们还解决了为提取器选择体系结构的问题。我们发现，具有剩余帧级连接的深度网络优于宽但相对浅的架构。本文还对现有的基于DNN的提取器系统进行了改进，以提高说话人识别的准确率。我们表明，作为嵌入后端，判别训练的相似性度量学习方法优于标准的LDA-PLDA方法。在野外演讲者和NIST SRE 2016评估集上获得的结果表明，当处理接近现实生活条件时，所提出的系统具有鲁棒性。

分类描述：Covers natural language processing. Roughly includes material in ACM Subject Class I.2.7. Note that work on artificial languages (programming languages, logics, formal systems) that does not explicitly address natural-language issues broadly construed (natural-language processing, computational linguistics, speech, text retrieval, etc.) is not appropriate for this area.

英文摘要：
  We investigate deep neural network performance in the textindependent speaker recognition task. We demonstrate that using angular softmax activation at the last classification layer of a classification neural network instead of a simple softmax activation allows to train a more generalized discriminative speaker embedding extractor. Cosine similarity is an effective metric for speaker verification in this embedding space. We also address the problem of choosing an architecture for the extractor. We found that deep networks with residual frame level connections outperform wide but relatively shallow architectures. This paper also proposes several improvements for previous DNN-based extractor systems to increase the speaker recognition accuracy. We show that the discriminatively trained similarity metric learning approach outperforms the standard LDA-PLDA method as an embedding backend. The results obtained on Speakers in the Wild and NIST SRE 2016 evaluation sets demonstrate robustness of the proposed systems when dealing with close to real-life conditions.
