摘要:

复调器乐中的演唱声检测是音乐信息检索的关键。为了训练鲁棒的人声检测器,在帧级标记有人声或非人声标签的大数据集是必不可少的。然而,帧级标记是耗时和劳动力昂贵的,导致很少有良好的标记数据集可用于歌唱语音检测(S-VD)。因此,我们提出了一种通过迁移学习的S-VD数据增强方法。在这项研究中,干净的语音片段与语音活动端点和单独的器乐片段被人工添加在一起,以模拟复调人声训练一个声乐/非声乐检测器。由于说话和唱歌之间的发音和发声不同,用人工数据集训练的人声检测器与人声与乐器伴奏一起唱歌的复调音乐不匹配。为了减少这种不匹配,使用迁移学习来将从人工语音加音乐训练集学到的知识迁移到小但匹配的复音数据集,即,演唱者与歌手通过转移相关知识来弥补S-VD中缺乏良好标记的训练数据,所提出的迁移学习数据增强方法可以提高S-VD的性能,F分数从89.5%提高到93.2%。

英文摘要:

Detecting singing-voice in polyphonic instrumental music is critical to music information retrieval. To train a robust vocal detector, a large dataset marked with vocal or non-vocal label at frame-level is essential. However, frame-level labeling is time-consuming and labor expensive, resulting there is little well-labeled dataset available for singing-voice detection (S-VD). Hence, we propose a data augmentation method for S-VD by transfer learning. In this study, clean speech clips with voice activity endpoints and separate instrumental music clips are artificially added together to simulate polyphonic vocals to train a vocal/non-vocal detector. Due to the different articulation and phonation between speaking and singing, the vocal detector trained with the artificial dataset does not match well with the polyphonic music which is singing vocals together with the instrumental accompaniments. To reduce this mismatch, transfer learning is used to transfer the knowledge learned from the artificial speech-plus-music training set to a small but matched polyphonic dataset, i.e., singing vocals with accompaniments. By transferring the related knowledge to make up for the lack of well-labeled training data in S-VD, the proposed data augmentation method by transfer learning can improve S-VD performance with an F-score improvement from 89.5% to 93.2%.
