Precise phonological knowledge of the Sri Lankan Portuguese Creole (SLPC) is limited. The earliest analysis of the language comes from the 19th and early 20th centuries, but since the research was based purely on written data, it lacks insight on how speech was actually produced. The only complete study that includes phonological analysis of native speakers seems to be Ian R Smith’s thesis which was published in 1978. His research surveyed the Creole-speaking people living in the Batticaloa area of Sri Lanka. It can be assumed, unless otherwise indicated, that the phonological information about SLPC in the section on vowels and consonants is solely from his thesis, due to the lack of similar resources of a precise nature.
