Project Description

The "MiiPro" study observes 4 acquainted first-born children of the same age, living close to each other in a neighborhood in the Tokyo area. Each child was observed separately at his/her home on a weekly basis from 1;2 to 3;0, and monthly or bi-monthly from 3;0 to 5;0. Each mother-child session lasted approx. 70 minutes. The present release covers the time span from 1;2 to 5;0 for Nanami, and 3;0 to 5;0 for Asato, Tomito, and Arika. For Arika, the ArikaF folder includes conversations with the father and ArikaM includes conversations with the mother.

The beginning and the end of the sessions include adult conversation (mother - investigator) occurring during the set up of the equipment (video camera and MD recorder) The maternal utterances directed to INV are marked by [+ bch]. The mother was given the instruction to play with the child, as she would normally do, animating her to talk. but to stay within the range of the video camera, and to avoid eating and drinking as well as noisy toys, TV, TV games and similar during the sessions. The investigator left during the observation. The most productive 60 minutes of each session are marked as "gem". Personal names are replaced by pseudonyms, last names replace by “N”. All utterances are transcribed on the base of the MD recordings in Japanese and Latin script (Miyata, 2012b), sound-linked with Sonic Mode, and provided with mor tiers (JMOR04.1 or later; please check the information in the Comment header tier; Miyata & Naka, 2014). MLU and DSSJ were computed with CLAN following the procedure explained in Miyata (2012a). The children's first names were replaced by pseudonyms.

The girl Nanami (NJD; 1;1.29 – 5;0.17) was observed monthly (total 65h 21min). The corpus includes 58 sessions with a total of 27,416 utterances of NJD and 58,324 utterances of MOT. Nanami's younger sister Juri (JUI; born when Nanami was 2;2) and her baby brother Kanta (KAN; born when Nanami was 3;6) were mostly present and sometimes took part in the conversation. Their transcribed utterances are not in JCHAT format and have not been checked for reliability.

Nisisawa, Hiro Yuki nisisawa@tokiwa.ac.jp
Miyata, Susanne smiyata@asu.aasa.ac.jp

The girl Arika (APR; 2;11.28 – 5;0.17) was observed monthly. Arika was born 13-MAY-1996. The ArikaM corpus includes 55 sessions with a total of 47,173 utterances of APR and 40,412 utterances of MOT (total 67h 45min). Arika's younger sister Fuyumi (FUY; born when Arika was 3;2) was often present and started to take part in the conversation in the later sessions. Fuyumi’s transcribed utterances are not in JCHAT format and have not been checked for reliability. A second corpus of conversations of Arika with her father (ArikaF corpus) is under work.
