Tra-la-Lyrics 2.0: Automatic Generation of Song Lyrics on a Semantic Domain

TLDR

Tra‑la‑Lyrics automatically generates song lyrics, originally focusing on rhythm matching without regard for semantic coherence. This work presents Tra‑la‑Lyrics 2.0, which generates lyrics grounded in a semantic domain specified by seed words. The authors integrated the original rhythm module into PoeTryMe, then evaluated rhythm, rhyme, and semantic coherence of the new lyrics against the original, and conducted a crowdsourced survey to assess perceived improvements. The new system produced lyrics with stronger semantic association to the seeds while preserving rhythm and rhyme, and crowdsourced feedback confirmed these improvements.

Abstract

Abstract Tra-la-Lyrics is a system that generates song lyrics automatically. In its original version, the main focus was to produce text where stresses matched the rhythm of given melodies. There were no concerns on whether the text made sense or if the selected words shared some kind of semantic association. In this article, we describe the development of a new version of Tra-la-Lyrics, where text is generated on a semantic domain, defined by one or more seed words. This effort involved the integration of the original rhythm module of Tra-la-Lyrics in PoeTryMe, a generic platform that generates poetry with semantically coherent sentences. To measure our progress, the rhythm, the rhymes, and the semantic coherence in lyrics produced by the original Tra-la-Lyrics were analysed and compared with lyrics produced by the new instantiation of this system, dubbed Tra-la-Lyrics 2.0. The analysis showed that, in the lyrics by the new system, words have higher semantic association among them and with the given seeds, while the rhythm is still matched and rhymes are present. The previous analysis was complemented with a crowdsourced evaluation, where contributors answered a survey about relevant features of lyrics produced by the previous and the current versions of Tra-la-Lyrics. Though tight, the survey results confirmed the improvements of the lyrics by Tra-la-Lyrics 2.0.
