摘要:

与经典参数方法相比,基于深度神经网络的声音事件定位框架已经显示出关于混响和噪声的增加的鲁棒性。特别是,经常性的架构,将时间背景的估计过程似乎是非常适合这项任务。本文提出了一种新的方法,利用注意力为基础的序列到序列模型的声音事件定位。这些类型的模型已成功地应用于自然语言处理和自动语音识别中的问题。在这项工作中,多声道音频信号被编码到一个潜在的表示,这是随后解码到一个序列的估计方向的到来。这里,注意力允许通过聚焦于与估计当前时间步处的声音事件的活动和到达方向相关的特定帧来捕获音频信号中的时间依赖性。该框架进行评估的声音事件本地化的三个公开可用的数据集。它产生优越的定位性能相比,国家的最先进的方法在消声和混响条件。

英文摘要:

Sound event localization frameworks based on deep neural networks have shown increased robustness with respect to reverberation and noise in comparison to classical parametric approaches. In particular, recurrent architectures that incorporate temporal context into the estimation process seem to be well-suited for this task. This paper proposes a novel approach to sound event localization by utilizing an attention-based sequence-to-sequence model. These types of models have been successfully applied to problems in natural language processing and automatic speech recognition. In this work, a multi-channel audio signal is encoded to a latent representation, which is subsequently decoded to a sequence of estimated directions-of-arrival. Herein, attentions allow for capturing temporal dependencies in the audio signal by focusing on specific frames that are relevant for estimating the activity and direction-of-arrival of sound events at the current time-step. The framework is evaluated on three publicly available datasets for sound event localization. It yields superior localization performance compared to state-of-the-art methods in both anechoic and reverberant conditions.
