Current automatic lyrics transcription (ALT) benchmarks focus exclusively on
word content and ignore the finer nuances of written lyrics including
formatting and punctuation, which leads to a potential misalignment with the
creative products of musicians and songwriters as well as listeners'
experiences. For example, line breaks are important in conveying information
about rhythm, emotional emphasis, rhyme, and high-level structure. To address
this issue, we introduce Jam-ALT, a new lyrics transcription benchmark based on
the JamendoLyrics dataset. Our contribution is twofold. Firstly, a complete
revision of the transcripts, geared specifically towards ALT evaluation by
following a newly created annotation guide that unifies the music industry's
guidelines, covering aspects such as punctuation, line breaks, spelling,
background vocals, and non-word sounds. Secondly, a suite of evaluation metrics
designed, unlike the traditional word error rate, to capture such phenomena. We
hope that the proposed benchmark contributes to the ALT task, enabling more
precise and reliable assessments of transcription systems and enhancing the
user experience in lyrics applications such as subtitle renderings for live
captioning or karaoke.

为了解决自动歌词转录中忽略了格式和标点等细微差别的问题，我们引入了 Jam-ALT，这是一个新的歌词转录基准，基于 JamendoLyrics 数据集，包括修订的转录以及用于评估的指标，旨在提高转录系统的准确性和可靠性。
