本文提出基于NGCC-PHAT的多目标TDOA特征学习方法,通过置换不变训练处理多个重叠声音事件,并在STARSS23数据集上验证其相比GCC-PHAT和SALSA-Lite能提升声音事件定位性能。

摘要:

使用麦克风阵列音频录音的声音事件定位与检测(SELD)系统依赖空间线索来确定声音事件的位置。因此,此类系统的定位性能在很大程度上取决于作为系统输入的音频特征的质量。我们提出一种基于神经广义互相关相位变换(NGCC-PHAT)的新特征,该特征学习适合定位的音频表示。通过将置换不变训练用于到达时间差(TDOA)估计问题,NGCC-PHAT能够为多个重叠声音事件学习TDOA特征。这些特征可以作为SELD网络中GCC-PHAT输入的直接替代。我们在STARSS23数据集上测试了我们的方法,并证明与使用标准GCC-PHAT或SALSA-Lite输入特征相比,定位性能有所提升。

英文摘要:

Sound event localization and detection (SELD) systems using audio recordings from a microphone array rely on spatial cues for determining the location of sound events. As a consequence, the localization performance of such systems is to a large extent determined by the quality of the audio features that are used as inputs to the system. We propose a new feature, based on neural generalized cross-correlations with phase-transform (NGCC-PHAT), that learns audio representations suitable for localization. Using permutation invariant training for the time-difference of arrival (TDOA) estimation problem enables NGCC-PHAT to learn TDOA features for multiple overlapping sound events. These features can be used as a drop-in replacement for GCC-PHAT inputs to a SELD-network. We test our method on the STARSS23 dataset and demonstrate improved localization performance compared to using standard GCC-PHAT or SALSA-Lite input features.
