摘要/Abstract

摘要：

为了解决现有鉴伪模型存在的泛化能力不强、检测准确率较低等难题,文章提出基于混合特征融合的多通道GRU伪造语音鉴别模型。该模型利用多通道挖掘不同输入特征的多尺度信息,同时引入注意力机制对多尺度特征进行融合并决策分类。在ASVspoof2019数据集上进行验证,所提方法对Logical Access伪造样本的检测准确率达到了96.30%,对Physical Access达到了87.33%,优于其他算法。实验结果证明,时频域特征融合的伪造语音检测方法能够学习更有效的真伪鉴别特征,获得更高的检测准确率。

Abstract:

In order to solve the problems of poor generalization ability and low detection accuracy of existing counterfeit authentication models, this article proposes a three-channel GRU forged voice identification model based on hybrid feature fusion. Validated on the ASVspoof2019 dataset, the accuracy of the proposed method reaches 96.30% for the detection of fake Logical Access samples and 87.33% for that of the fake Physical Access samples, which is better than other algorithms. The experimental results prove that the fake voice detection method based on time-frequency domain feature fusion can learn more effective authenticity identification features and obtain higher detection accuracy.

Key words: speech forgery detection, multi-channel GRU, feature fusion, deep learning
