What is LIPPS?
 

The LIPPS Group (Language Interaction in Plurilingual and Plurilectal Speakers) is an international group of researchers whose long term aim is to set up a computerised database of bilingual mixed-language (code-switching) data which will be available to all researchers, and to develop appropriate transcription standards and software to enable the maximum development and use of the database. The group was set up in 1994.

In 2000 the LIPPS Group published the LIDES Coding Manual, ‘A Document for Preparing and Analysing Language Interaction Data’, as a special issue of the International Journal of Bilingualism (Volume 4, Number 2 June, 2000; ISSN 1367-0069). The LIDES Coding Manual contains the recommendations developed so far for transcribing and encoding bilingual data. The LIDES recommendations are based on an  successful existing system for child language data, CHILDES.

Could LIPPS be of interest to me?

It could, if you have bilingual or multilingual data or want to do research on such data. The LIPPS guidelines can provide you with a ready-made system of transcription, and if you follow the recommended format, you will also be able to run computer programs (freely downloadable) which can help you to analyse your data. LIPPS also aims to establish a database of language interaction data in standard format, which will be available to anyone doing research in this field. You will be able to use the data in the database which others have collected and transcribed, and if you have suitable data of your own, we encourage you to share it with other researchers by placing it in the database.

Who is involved in LIPPS?

The LIPPS group has a Steering Committee and an Advisory Committee. The LIDES Coding Manual was the joint work of 11 authors (to see their photographs, click here). Anyone is welcome to become involved with LIPPS and LIDES if they have an interest in the area.

Comments and questions about LIPPS and LIDES
may be sent to any of the Steering Committee: Mark Sebba, Melissa Moyer, Roeland van Hout, Penelope Gardner-Chloros.
