说话人识别技术是生物特征识别中非常热门的一个方向,一直以来随着信息技术的发展而不断得到推广和应用。尤其是当今移动互联网时代的到来,更是使说话人识别技术的应用场景不断扩大,其实用价值越来越高。本文研究的主要是基于i-vector/PLDA的说话人识别,研究如何对PLDA(ProbabilisticLinearDiscriminantAnalysis)模型进行优化,并通过引入一种迁移学习(TransferLearning)方法解决数据量不足时导致训练出来的PLDA模型准确度急剧下降的问题。 本文首先介绍说话人识别技术中的一些经典系统如GMM-UBM系统,GMM-SVM系统以及基于i-vector...Speaker recognition is an important technology of biometric authentication, which is used more and more widely in many areas, especially on the era of mobile Internet. Based on the i-vector/PLDA speaker recognition algorithm, we study how to optimize the PLDA model and apply a transfer learning method to solve the training problem of PLDA model when there are insufficient amount of data. We first...学位:工程硕士院系专业:信息科学与技术学院_工程硕士(计算机技术)学号:3152013115...
