NUS-48E

We hereby present the NUS Sung and Spoken Lyrics Corpus (NUS-48E corpus) as the first step toward a large, phonetically annotated corpus for singing voice research. The corpus is a 169-min collection of audio recordings of the sung and spoken lyrics of 48 (20 unique) English songs by 12 subjects and a complete set of transcriptions and duration annotations at the phone level for all recordings of sung lyrics, comprising 25,474 phone instances. Using the NUS-48E corpus, we conducted a preliminary, quantitative study on the comparison between singing voice and speech.
