The CORDIAL-SIN is a dialect corpus of European Portuguese. The materials for this corpus were drawn from the recordings of dialect speech collected by the Research Group on Linguistic Variation at Centro de Linguística da Universidade de Lisboa (CLUL) as fieldwork interviews for linguistic atlases between 1974 and 2004 in more than 200 locations in the Portuguese territory.

The CORDIAL-SIN compiles a geographically representative body of selected excerpts of spontaneous and semi-directed speech from these interviews. The informants were aged, received little instruction, lived in a rural area, and were born and raised in the location of the interview.

The corpus amounts to 600,000 words, collected from 42 locations within the continental territory of Portugal and the archipels of Madeira and Azores. The data have been made available in the following formats: two kinds of orthographic transcripts (more or less detailed for the marking up of spoken language phenomena) and PoS tagged texts. In the future, the syntactic annotation for the corpus, which is currently (April 2010) in progress, will also be available.
