摘要:

本文的目标是适应扬声器嵌入解决问题的扬声器diarisation。说话人嵌入的质量对说话人拨号系统的性能至关重要。尽管如此,在该领域中的先前工作已经直接使用了仅被设计为在说话人验证任务上有效的嵌入。在本文中,我们提出了三种技术,可以用来更好地适应diarisation的扬声器嵌入:降维,基于注意力的嵌入聚合,和非语音聚类。在各种具有挑战性的数据集上进行了广泛的实验。结果表明,所有这三种技术都对Diarisation系统的性能做出了积极贡献,在基线上的Diarisation错误率方面平均相对改善了25.07%。

英文摘要:

The goal of this paper is to adapt speaker embeddings for solving the problem of speaker diarisation. The quality of speaker embeddings is paramount to the performance of speaker diarisation systems. Despite this, prior works in the field have directly used embeddings designed only to be effective on the speaker verification task. In this paper, we propose three techniques that can be used to better adapt the speaker embeddings for diarisation: dimensionality reduction, attention-based embedding aggregation, and non-speech clustering. A wide range of experiments is performed on various challenging datasets. The results demonstrate that all three techniques contribute positively to the performance of the diarisation system achieving an average relative improvement of 25.07% in terms of diarisation error rate over the baseline.
