L1-L2map: A Tool for Multi-lingual Contrastive Analysis

The present article describes the development of L1-L2map, a multi-lingual contrastive analysis tool. It uses the phoneme inventories of a large number of languages, but also contains more detailed phonetic information. An example of this is the information about the syllable positions in which the sounds can occur in a given language, which is very useful for computer-assisted pronunciation training (CAPT). The tool is available through a wiki and can be extended to include new languages. The result from contrastive analysis is used in CAPT to guide language learners through pronunciation exercises depending on their native language.
