Computational Pronunciation Analysis in Sung Utterances (2106.10977v1)

Abstract: Recent automatic lyrics transcription (ALT) approaches focus on building stronger acoustic models or in-domain LLMs, while the pronunciation aspect is seldom touched upon. This paper applies a novel computational analysis on the pronunciation variances in sung utterances and further proposes a new pronunciation model adapted for singing. The singing-adapted model is tested on multiple public datasets via word recognition experiments. It performs better than the standard speech dictionary in all settings reporting the best results on ALT in a capella recordings using n-gram LLMs. For reproducibility, we share the sentence-level annotations used in testing, providing a new benchmark evaluation set for ALT.
