摘要翻译：
大多数以前的歌词与音频对齐方法都使用预先开发的自动语音识别(ASR)系统，该系统在使语音模型适应单个歌手方面存在一些先天困难。以往研究中缺少的一个重要方面是歌唱语音中重复元音模式的自学习性，即元音部分的使用比辅音部分的使用更一致。基于此，我们的系统首先以标准声学特征的自相似性为输入，基于加权对称非负矩阵分解（WS-NMF）学习元音序列的判别子空间。然后，我们利用一种最新的计算机视觉技术--典型时间规整(CTW)来寻找文本和声学序列之间的最佳时空转换。用韩语和英语数据集进行的实验表明，在预先开发的、无监督的、歌唱源分离后使用该方法比现有的无监督方法和基于ASR的系统取得了更好的效果。

英文摘要：
  Most of the previous approaches to lyrics-to-audio alignment used a pre-developed automatic speech recognition (ASR) system that innately suffered from several difficulties to adapt the speech model to individual singers. A significant aspect missing in previous works is the self-learnability of repetitive vowel patterns in the singing voice, where the vowel part used is more consistent than the consonant part. Based on this, our system first learns a discriminative subspace of vowel sequences, based on weighted symmetric non-negative matrix factorization (WS-NMF), by taking the self-similarity of a standard acoustic feature as an input. Then, we make use of canonical time warping (CTW), derived from a recent computer vision technique, to find an optimal spatiotemporal transformation between the text and the acoustic sequences. Experiments with Korean and English data sets showed that deploying this method after a pre-developed, unsupervised, singing source separation achieved more promising results than other state-of-the-art unsupervised approaches and an existing ASR-based system.
