Das IFCASL-Korpus als phonetisches Lernerkorpus

Phonetic learner corpora represent a special type of spoken learner corpora by providing detailed phonetic and phonological annotation in the form of phonetic transcription as well as the segmentation and labelling of the speech signal on the levels of segments, syllables, words and sentences. This time-consuming post-processing enables a better acoustic analysis of the data and provides many options for using audio data in teaching foreign languages. It also offers good opportunities to develop tools for computer-aided pronunciation training. The possibilities and restrictions of phonetic learner corpora are illustrated with the bidirectional German–French IFCASL corpus.
