This project is funded by a European Young Investigator Award to Mirjam Ernestus. The corpus was recorded by Francisco Torreira at the Laboratoire de Phonétique et Phonologie (UMR7018) in Paris during November 2008 as part of his dissertation work at the Radboud University Nijmegen. The orthographic transcription was carried out in collaboration with Martine Adda-Decker (CNRS-LIMSI, France).
