论文摘要
在本文中，我们讨论了带宽扩展与说话者识别任务的相关性。主要是我们要研究是否可以识别出频带扩展的声音。为此，我们创建了两个不同的数据库（微音和ISDN）的语音信号，它们是从电话带宽（[300，3400] Hz）扩展到完整带宽（[100，8000] Hz）的带宽。我们已经评估了不同的参数化，并且发现MELCEPST参数化可以在几种情况下利用带宽扩展算法。
In this paper we discuss the relevance of bandwidth extension for speaker identification tasks. Mainly we want to study if it is possible to recognize voices that have been bandwith extended. For this purpose, we created two different databases (microphonic and ISDN) of speech signals that were bandwidth extended from telephone bandwidth ([300, 3400] Hz) to full bandwidth ([100, 8000] Hz). We have evaluated different parameterizations, and we have found that the MELCEPST parameterization can take advantage of the bandwidth extension algorithms in several situations.
