Sound Event Detection and Localization with Distance Estimation
European Signal Processing Conference(2024)
Abstract
Sound Event Detection and Localization (SELD) is a combined task ofidentifying sound events and their corresponding direction-of-arrival (DOA).While this task has numerous applications and has been extensively researchedin recent years, it fails to provide full information about the sound sourceposition. In this paper, we overcome this problem by extending the task toSound Event Detection, Localization with Distance Estimation (3D SELD). Westudy two ways of integrating distance estimation within the SELD core - amulti-task approach, in which the problem is tackled by a separate modeloutput, and a single-task approach obtained by extending the multi-ACCDOAmethod to include distance information. We investigate both methods for theAmbisonic and binaural versions of STARSS23: Sony-TAU Realistic SpatialSoundscapes 2023. Moreover, our study involves experiments on the loss functionrelated to the distance estimation part. Our results show that it is possibleto perform 3D SELD without any degradation of performance in sound eventdetection and DOA estimation.
