This study identifies the phonological system in the idiolects of three native speakers of the Acadian dialect in southwest Nova Scotia, on the coast of Baie Sainte-Marie. The study also highlights the specificity of the phonological system by comparing it with the speech of Acadians in Moncton, New Brunswick and with standard French. The informants were two women, aged 89 and 80 years, and a man, aged 85. They were chosen because they were considered to be representative of speakers whose language would be least influenced by standard French and English. The research followed the theoretical principles and analytical methods of functional linguistics. In addition to the analysis of the phonological system and the comparisons, the report provides the following: (1) objectives of the study, (2) a description of the region under study, (3) the present state of research on the phonological system of the Baie Sainte-Marie region, (4) the informants and the corpus of the study, and (5) a discussion of functionalism.
