Project Description

The NINJAL-Okubo data were collected by the National Institute for Japanese Language and Linguistics for the purpose of observation of the language and acquisition behaviour of pre-school children. The study was conducted by Ai Okubo. The data consist of the speech of a first-born boy (Taachan, born March 3, 1974) between his first and fourth birthday and were collected in cooperation with his mother over a three-year period starting in 1975, The study contains data of about two hours per month, recorded on several days during the month. The transcription is based on cassette tape recordings (Sony TC 1000B), and was performed by the mother. Explanations of the situation were added where necessary. The child’s utterances are transcribed close to actual pronunciation.

The data are published in 6 volumes:

I : Part 1. 24 Hour Record of Utterances of a Child Recorded on his Second Birthday

Part 2. 24 Hour Record of Utterances of a Child Recorded on his Third Birthday

II: 24 Hour Record of Utterances of a Child Recorded on the Day before his Fourth Birthday

VI: A Case Study of a Child's Utterances from 3;6 to 3;11 Years
