Channel Robust Text-Independent Speaker Recognition and Application [PDF]
由于信息安全问题的不断涌现,在公共安全、金融、商业等领域,基于生物特征认证技术的产品需求逐渐膨胀。说话人识别作为唯一适合远程认证的技术,逐渐被各个领域所接受,并开始得到应用。但实用系统中,各式各样的语音采集设备与传输信道差异,使得训练语音与测试语音之间存在信道失配的情况,导致说话人识别性能急剧下降。这便是说话人识别中的跨信道问题,它也是影响说话人识别性能最重要的因素之一。因此,如何在最大程度上降低跨信道对识别性能的影响,将是本课题的研究重点。 本文从特征域、模型域及得分域这三个层面 ...
