摘要翻译：
J向量已被证明在短时程语音的文本相关说话人验证中是非常有效的。然而，目前最先进的后端分类器，如联合贝叶斯模型，不能充分利用这些深层特征。在本文中，我们推广了标准的联合贝叶斯方法来显式地联合建模J-向量中的多个方面的信息。在我们的推广中，J向量是由一个包含几种潜在变量的生成双联合贝叶斯（DoJoBa）模型导出的结果。使用DoJoBa，我们能够显式地构建一个模型，该模型可以组合来自J向量的多个异构信息。在验证步骤中，我们计算了描述两个J向量是否具有一致标记的似然度。在公开的RSR2015数据语料库上的实验结果表明，该方法对冒名顶替错误和冒名顶替正确的情况分别能获得0.02%EER和0.02%EER。

英文摘要：
J-vector has been proved to be very effective in text-dependent speaker verification with short-duration speech. However, the current state-of-the-art back-end classifiers, e.g. joint Bayesian model, cannot make full use of such deep features. In this paper, we generalize the standard joint Bayesian approach to model the multi-faceted information in the j-vector explicitly and jointly. In our generalization, the j-vector was modeled as a result derived by a generative Double Joint Bayesian (DoJoBa) model, which contains several kinds of latent variables. With DoJoBa, we are able to explicitly build a model that can combine multiple heterogeneous information from the j-vectors. In verification step, we calculated the likelihood to describe whether the two j-vectors having consistent labels or not. On the public RSR2015 data corpus, the experimental results showed that our approach can achieve 0.02\% EER and 0.02\% EER for impostor wrong and impostor correct cases respectively.
