We present a database of parallel recordings of speech and singing, collected and released by the Human Language Technology (HLT) laboratory at the National University of Singapore (NUS), that is called NUS-HLT Speak-Sing (NHSS) database. This database consists of recordings of sung vocals of English pop songs, the spoken counterpart of lyrics of the songs read by the singers in their natural reading manner, and manually prepared utterance-level and word-level annotations. The audio recordings in the NHSS database correspond to a total of 100 songs sung and spoken by 10 singers, resulting in total of 7 hours audio data. There are 5 male and 5 female singers, singing and reading the lyrics of 10 songs each. We release this database to the public for research activities.
