论文摘要
本文介绍了一项有关几个参数化的鲁棒性的详尽研究,其中一个新的数据库是专门为说话者识别应用程序而获得的。该数据库包括以下差异:不同的记录会话(包括电话和微音录音),录制室和语言(已从双语扬声器集获得)。这项研究是在文本独立说话者验证应用程序中使用协方差矩阵进行的。它揭示了几种参数化的组合可以改善所有情况下的鲁棒性。
This paper presents an exhaustive study about the robustness of several parameterizations, with a new database specially acquired for the purpose of a speaker recognition application. This database includes the following variations: different recording sessions (including telephonic and microphonic recordings), recording rooms, and languages (it has been obtained from a bilingual set of speakers). This study has been performed with covariance matrices in a text independent speaker verification application. It reveals that the combination of several parameterizations can improve the robustness in all the scenarios.
