A pilot study for a Corpus of Dutch Aphasic Speech (CoDAS)

In this paper, a pilot study for the development of a corpus of Dutch Aphasic Speech (CoDAS) is presented. Given the lack of resources of this kind not only for Dutch but also for other languages, CoDAS will be able to set standards and will contribute to the future research in this area. We have established the basic requirements with respect to text types, metadata, and annotation levels that CoDAS should fulfill. Given the special character of the speech contained in CoDAS, we cannot simply carry over the design and annotation protocols of existing corpora, such as the Spoken Dutch Corpus (CGN) or CHILDES. However, they have been taken as starting point. We have investigated whether and how the procedures and protocols for the orthographic transcription and the part-of-speech tagging used for the CGN should be adapted in order to annotate and transcribe aphasic speech properly.
