摘要:

知情说话人提取的目的是从混合源中提取目标语音信号,给出关于所需说话人的先验知识。最近的基于深度学习的方法利用说话者判别模型,该模型将目标说话者发出的参考片段映射到封装目标说话者特征的单个嵌入向量中。然而,这种建模故意忽略了参考信号的时变特性。在这项工作中,我们假设一个参考信号是可用的,是时间相关的目标信号。为了考虑到这种相关性,我们提出了一个时变源判别模型,捕获的参考信号的时间动态。我们还表明,现有的方法和所提出的方法可以推广到非语音源以及。实验结果表明,所提出的方法显着提高提取性能时,应用在声学回声减少的情况下。

英文摘要:

Informed speaker extraction aims to extract a target speech signal from a mixture of sources given prior knowledge about the desired speaker. Recent deep learning-based methods leverage a speaker discriminative model that maps a reference snippet uttered by the target speaker into a single embedding vector that encapsulates the characteristics of the target speaker. However, such modeling deliberately neglects the time-varying properties of the reference signal. In this work, we assume that a reference signal is available that is temporally correlated with the target signal. To take this correlation into account, we propose a time-varying source discriminative model that captures the temporal dynamics of the reference signal. We also show that existing methods and the proposed method can be generalized to non-speech sources as well. Experimental results demonstrate that the proposed method significantly improves the extraction performance when applied in an acoustic echo reduction scenario.
