摘要:

扬声器日志化(SD)包括根据扬声器身份来分割或分段输入音频突发。在本文中,我们专注于SD问题的关键任务,这是音频分割过程,并提出了一个解决方案的变化点检测(CPD)问题。我们经验证明的负相关性增加的扬声器和召回和F1分数测量的数量。这种负相关性被证明是一个大规模的实验评估过程的结果,这说明它的优越性,最近开发的基于语音的解决方案。为了克服扬声器的数量问题,我们提出了一个强大的解决方案的基础上,一种新的自然语言处理(NLP)技术,以及元数据特征提取过程,而不是一个单独的声乐为基础。据我们所知,我们是第一个提出基于智能NLP的解决方案的人,该解决方案(I)用希伯来语的数据集解决CPD问题,(II)解决SD问题的CPD变体。我们经验表明,基于两个不同的数据集,我们的方法是能够准确地识别的CPD在音频突发与82.12%和89.02%的成功率在召回和F1分数测量。

英文摘要:

Speaker Diarization (SD) consists of splitting or segmenting an input audio burst according to speaker identities. In this paper, we focus on the crucial task of the SD problem which is the audio segmenting process and suggest a solution for the Change Point Detection (CPD) problem. We empirically demonstrate the negative correlation between an increase in the number of speakers and the Recall and F1-Score measurements. This negative correlation is shown to be the outcome of a massive experimental evaluation process, which accounts its superiority to recently developed voice based solutions. In order to overcome the number of speakers issue, we suggest a robust solution based on a novel Natural Language Processing (NLP) technique, as well as a metadata features extraction process, rather than a vocal based alone. To the best of our knowledge, we are the first to propose an intelligent NLP based solution that (I) tackles the CPD problem with a dataset in Hebrew, and (II) solves the CPD variant of the SD problem. We empirically show, based on two distinct datasets, that our method is abled to accurately identify the CPDs in an audio burst with 82.12% and 89.02% of success in the Recall and F1-score measurements.
