摘要：Studies in the field of language acquisition and language disorders are part of different and complementary theoretical frameworks. These approaches vary from experimental to natural resource methods. The tools developed in the branch of corpus linguistics can be used to describe and analyse clinical situations. Furthermore,they can be used by speech and language pathologists in the context of their professional practices. After explaining methods for the transcription of natural data,we show tools enabling the quantitative and qualitative analysis of language practices. To this end,the focus will be placed on CLAN software and on the relevance of linguistic expertise as a means of evaluating professional practices.
