Project Description

The UH-UT Child Second Language Acquisition Database (UH-UT CSLAD) was created by Yuki Hirose Lab (Univ. of Tokyo) in collaboration with Theres Grüter (Department of Second Language Studies, University of Hawaii at Manoa). The aim of this database is to examine a child’s second language development longitudinally. The corpus contains spontaneous speech by a Japanese-speaking boy, who temporarily relocated from Japan to the U.S. at age 7 years 10 months with minimal previous experience with English.

Terms of use

• Retaining the research target’s dignity: The target’s second language is still underdeveloped, so please refrain from using the data to ridicule their language ability.
• The appropriateness of the utterance: The content of the recorded utterances reflects a child’s extremely immature view of the world; thus, we kindly ask for your understanding on this matter. We have tried to omit any content that may be offensive towards specific persons or groups, but if you find anything problematic, please contact us at hirose@boz.c.u-tokyo.ac.jp.
• Additionally, please read the Basic Principles concerning ethics (https://www.talkbank.org/share/ethics.html) when using data in TalkBank, including CHILDES, and avoid deviating from those rules.

Precautions and Disclaimers

The transcription is done based on the recordings, but the accuracy may be affected due to multiple factors such as the conversation overlapping, sound environment, or the utterance not being clear because it is spoken by a child developing his second language. If in doubt of the transcription accuracy, please refer to the videos.

In terms of the transcription and chat file itself, all team members followed the same instruction manual, however, the annotation may slightly vary by each contributor, resulting in inconsistency between files. For example, if the utterance has a grammatical error, there may be included annotations that edit the utterance to make it grammatically correct, but the degree of including these annotations differs by the contributor.

The UH-UT CSLAD Development Team shall not be liable for any such aforementioned inaccuracy, incompleteness, inadequacy and the unfairness of the data and the information presented in the UH-UT CSLAD.

The data and the information of the UH-UT CSLAD may be changed or modified without any prior notice, and the UH-UT CSLAD Site may be discontinued or closed without any prior notice.
