Multitask Detection of Speaker Changes, Overlapping Speech and Voice Activity Using Wav2vec 2.0

ICASSP 2023accepted

Self-supervised learning approaches have lately achieved great success on a broad spectrum of machine learning problems. In the field of speech processing, one of the most successful recent self-supervised models is wav2vec 2.0. In this paper, we explore the effectiveness of this model on three basi…

Convolutional Neural Network for speaker change detection in telephone speaker diarization system

ICASSP 2017accepted

The aim of this paper is to propose a speaker change detection technique based on Convolutional Neural Network (CNN) and evaluate its contribution to the performance of a speaker diarization system for telephone conversations. For the comparison we used an i-vector based speaker diarization system.…
