摘要:

音频特征已被证明对提高自动主题分割系统的性能是有用的。本研究探讨了新的任务,使用音频嵌入的自动化,局部连贯分割的广播节目。我们在来自不同领域的三个数据集上使用多类分类任务创建了三个不同的音频嵌入生成器。我们评估了音频嵌入的主题分割性能,并将其与纯文本基线进行比较。我们发现,包括通过非语音声音事件分类任务生成的音频嵌入的设置在F1测量中显著优于我们的纯文本基线32.3%。此外,我们发现,不同的分类任务产生不同的分割性能的音频嵌入。

英文摘要:

Audio features have been proven useful for increasing the performance of automated topic segmentation systems. This study explores the novel task of using audio embeddings for automated, topically coherent segmentation of radio shows. We created three different audio embedding generators using multi-class classification tasks on three datasets from different domains. We evaluate topic segmentation performance of the audio embeddings and compare it against a text-only baseline. We find that a set-up including audio embeddings generated through a non-speech sound event classification task significantly outperforms our text-only baseline by 32.3% in F1-measure. In addition, we find that different classification tasks yield audio embeddings that vary in segmentation performance.
