Explainable by-design Audio Segmentation through Non-Negative Matrix Factorization and Probing
Martin Lebourdais, Théo Mariotte, Antonio Almudévar +2
Audio segmentation is a key task for many speech technologies, most of which are based on neural networks, usually considered as black boxes, with high-level performances. However,…
Channel-Combination Algorithms for Robust Distant Voice Activity and Overlapped Speech Detection
Théo Mariotte, Anthony Larcher, Silvio Montrésor +1
Voice Activity Detection (VAD) and Overlapped Speech Detection (OSD) are key pre-processing tasks for speaker diarization. In the meeting context, it is often easier to capture spe…
An Explainable Proxy Model for Multiabel Audio Segmentation
Théo Mariotte, Antonio Almudévar, Marie Tahon +1
Audio signal segmentation is a key task for automatic audio indexing. It consists of detecting the boundaries of class-homogeneous segments in the signal. In many applications, exp…
