摘要:

在这封信中,我们提出了一个声道长度(Vocal Tract Length,VQ)扰动方法的文本相关的说话人确认(TD-SV),其中一组TD-SV系统的训练,每个VQ因子一个,和分数级融合应用于作出最终决定。接下来,我们探索通过训练具有自监督目标的深度神经网络提取的瓶颈(BN)特征,自回归预测编码(APC),用于TD-SV,并将其与研究良好的说话人判别BN特征进行比较。然后将该方法应用于APC和说话人判别BN特征。最后,我们将在MFCC上训练的微扰系统与分数域中的两个BN特征相结合。实验在TD-SV的RedDots挑战2016数据库上进行,使用高斯混合模型-通用背景模型和i-vector技术的短话语。结果表明,所提出的方法显着优于基线。

英文摘要:

In this letter, we propose a vocal tract length (VTL) perturbation method for text-dependent speaker verification (TD-SV), in which a set of TD-SV systems are trained, one for each VTL factor, and score-level fusion is applied to make a final decision. Next, we explore the bottleneck (BN) feature extracted by training deep neural networks with a self-supervised objective, autoregressive predictive coding (APC), for TD-SV and compare it with the well-studied speaker-discriminant BN feature. The proposed VTL method is then applied to APC and speaker-discriminant BN features. In the end, we combine the VTL perturbation systems trained on MFCC and the two BN features in the score domain. Experiments are performed on the RedDots challenge 2016 database of TD-SV using short utterances with Gaussian mixture model-universal background model and i-vector techniques. Results show the proposed methods significantly outperform the baselines.
