The Corpus
One aim of the IFCASL project is to construct a corpus of native and non-native speech for the language pair French-German. Our survey shows that no suitable corpus, in terms of size and coverage, is currently available for the target language pair.
Our design of such a corpus has three aims:
- We will bring to the research community two non-native corpora for the French-German language pair, whereas most studies have focused on English.
- The corpora will be informed by in-depth phonetic knowledge to predict the types of errors made by French and German learners.
- The corpora can further be used by the research community for the recognition of non-native speech.
