The no train no-gain system for O-cocosda and VLSP 2022 A-MSV shared task: Asian multilingual speaker verification

This paper proposes a semi-supervised multilingual speaker verification (MSV) system submitted for the 2 tasks, MSV for the Asian language inside the training set (T01) and outside the training set (T02) in O-COCOSDA and VLSP challenge 2022. To solve the problem, our strategy is training a baseline acoustic model with given labeled data (MSV CommonVoice) and fine-tuning the trained acoustic model with both given labeled data and given unlabeled data (MSV Youtube).
