摘要:

近年来,自动歌词对齐方法的准确性已经大大提高。然而,许多当前方法采用为自动语音识别(ASR)设计的框架,并且不利用音乐特有的属性。音高是歌唱声音的一个重要的音乐属性,但它往往被忽视,目前的系统作为歌词内容被认为是独立的音高。然而,在实践中,两者之间存在时间相关性,因为音符开始通常与音素开始相关。同时,音高通常在地面实况数据中以高时间准确度注释,而歌词的定时通常仅在行(或词)级别可用。在本文中,我们提出了一个多任务的学习方法,歌词对齐,结合音高,从而可以利用一个新的高度准确的时间信息源。我们的结果表明,我们的方法确实提高了对齐结果的准确性。作为一个额外的贡献,我们表明,在强制对齐算法中集成边界检测减少了交叉线误差,从而进一步提高了精度。

英文摘要:

In recent years, the accuracy of automatic lyrics alignment methods has increased considerably. Yet, many current approaches employ frameworks designed for automatic speech recognition (ASR) and do not exploit properties specific to music. Pitch is one important musical attribute of singing voice but it is often ignored by current systems as the lyrics content is considered independent of the pitch. In practice, however, there is a temporal correlation between the two as note starts often correlate with phoneme starts. At the same time the pitch is usually annotated with high temporal accuracy in ground truth data while the timing of lyrics is often only available at the line (or word) level. In this paper, we propose a multi-task learning approach for lyrics alignment that incorporates pitch and thus can make use of a new source of highly accurate temporal information. Our results show that the accuracy of the alignment result is indeed improved by our approach. As an additional contribution, we show that integrating boundary detection in the forced-alignment algorithm reduces cross-line errors, which improves the accuracy even further.
