Joana and Inês were recorded and partly transcribed by Maria João Freitas. The data were later and further transcribed and revised by Susana Correia, Teresa Costa and Maria João Freitas. For information on early transcriptions and analyses, see European Portuguese-Freitas in this manual and Freitas (1997).
This corpus is contained within the Acquisition of European Portuguese Databank (AcEP – www.clul.ul.pt/en/research-teams/476-acquisition-of-european-portuguese- databank), in CLUL's research group ANAGRAMA. The research work underlying Correia, Costa & Freitas (2010) was funded by Portuguese Science Foundation (research project PTDC/LIN/68024/2006) and two individual PhD research grants awarded to Susana Correia (SFRH/BD/21696/2005) and Teresa Costa (SFRH/BD/2844/2006) by the same Foundation.
Correia, Costa & Freitas (2010) contains data from 5 European Portuguese monolingual children during 135 recording sessions. The children’s speech was recorded every other week in the case of João and Luma, and monthly in the case of Inês, Clara and Joana. The data were recorded at the children’s homes, during spontaneous speech. The mother and/or caretaker and the researcher were present during the recording sessions.
The data were manually entered into the Phon application. Orthographic and phonetic transcriptions were made of the target and children's actual forms. The sessions were transcribed and exchanged between two transcribers for revisions. Each transcriber was responsible for transcribing 50% of the children's speech and revising the other 50%. In dubious cases, a third researcher carried out a blind transcription and, in the case of persistent indecision, that utterance was marked with an asterisk (*) as unintelligible.
All of the specific research questions formulated in Costa (2010) were related to the development of segmental properties (place and manner features) in Portuguese children. The analytic tools available through the Phon application enabled the researcher to extract information on the general order of acquisition of the EP consonantal inventory and the segmental shape of early words. The analytic features used in the study were: (i) searching and analyzing consonantal place and manner features in onset position; (ii) discriminating between homorganic and non-homorganic feature combinations at the word-level; (iii) searching and analyzing consonantal place and manner features, discriminating between stressed and unstressed syllables; (iv) searching/analyzing consonant harmony and metathesis in children's speech.
The research questions underlying Correia (2010) deal with the identification of and order of acquisition for primary word stress and the study of the early shape of prosodic words in Portuguese children. The analytic features used in this study were: (i) searching for and analyzing the number of words uttered by the children; (ii) searching for and analyzing the number of syllables within a word; (iii) searching for and analyzing the syllable structure in different word positions; (iv) searching for and analyzing stress patterns.
Only audio files and orthographic/phonetic transcriptions are public and available online. Access to video recordings is not allowed (for any further details on this issue, please contact the AcEP- Acquisition of European Portuguese Databank Project Director – see contacts and website given above).
