The Ramalho – EP corpus was gathered in the context of Ana Margarida Ramalho’s PhD research project (Ramalho 2017; http://rdpc.uevora.pt/handle/10174/23564), supervised by M. J. Freitas, D. Alves and F. Gonçalves. This research project was developed at Centro de Linguística da Universidade de Lisboa (CLUL) and followed the criteria assumed within the Cross-linguistic Child Phonology Project, hosted by the University of British Columbia (UBC) and coordinated by B. Bernhardt and J. Stemberger. The research was supported by Fundação para a Ciência e Tecnologia (PEst-OE/LIN/UI0214/2013 and UID/LIN/00214/2013; FCT individual PhD research grant SFRH/BD/88966/2012) and by the Social Sciences and Humanities Research Council of Canada. The RAMALHO - EP corpus was edited in PHONBANK (B. MacWhinney (Carnegie Mellon) and Y. Rose (University of Newfoundland)); it  contains experimental cross-sectional production data from 87 typically developing Portuguese children from the Lisbon area, all EP monolinguals, aged 2;11 to 6;04, with no history of hearing or language deficits or disorders.
