Korpora gesprochener Sprache von/für DaF-LernerInnen. Überblick über mutter- und lernersprachliche Korpora im Kontext von Deutsch als Fremdsprache

The aim of the present paper is to provide an overview (updated to April 2017) of the corpora of spoken German, which are relevant to the teaching of German as a foreign language and freely available on the Internet. These include, on the one hand, the L1 corpora, which are useful for designing syllabuses, developing authentic teaching materials and for direct application in the classroom, and on the other, L2 corpora for the study of second language acquisition. The following aspects are presented and discussed: scope and representativeness of the corpus; types of discourse, speakers and varieties; transcription, annotation and metadata; available query tools and download options; possible uses in the classroom; and publications. With respect to the L1 corpora, FOLK and the corpus "Gesprochene Sprache für die Auslandsgermanistik" provide a sufficient basis for research and teaching. However, it would be desirable to supplement the conversationanalytic approach with phonetically and prosodically annotated corpora. With regard to the web-based L2 corpora (GeWiss and BeMaTaC) the range of communication types (examination interview, student and expert presentation, map task dialogue) and L1 languages (English, Polish, partly Bulgarian and Italian) is quite limited. Here, it would be desirable to set up further corpora to comprehensively investigate the acquisition of German as a foreign or second language
