VoxVietnam: a Large-Scale Multi-Genre Dataset for Vietnamese Speaker Recognition
This addresses the lack of genre-diverse resources for Vietnamese speaker recognition, enabling studies on multi-genre effects, though it is incremental as it focuses on dataset creation rather than novel methods.
The paper tackles the problem of speaker recognition vulnerability to multi-genre variations by introducing VoxVietnam, a large-scale multi-genre dataset for Vietnamese with over 187,000 utterances from 1,406 speakers, and shows that incorporating it into training significantly increases performance.
Recent research in speaker recognition aims to address vulnerabilities due to variations between enrolment and test utterances, particularly in the multi-genre phenomenon where the utterances are in different speech genres. Previous resources for Vietnamese speaker recognition are either limited in size or do not focus on genre diversity, leaving studies in multi-genre effects unexplored. This paper introduces VoxVietnam, the first multi-genre dataset for Vietnamese speaker recognition with over 187,000 utterances from 1,406 speakers and an automated pipeline to construct a dataset on a large scale from public sources. Our experiments show the challenges posed by the multi-genre phenomenon to models trained on a single-genre dataset, and demonstrate a significant increase in performance upon incorporating the VoxVietnam into the training process. Our experiments are conducted to study the challenges of the multi-genre phenomenon in speaker recognition and the performance gain when the proposed dataset is used for multi-genre training.
