This contribution presents part of the work initiated at CTT on the development of speech technology to assist non-native speakers in learning Swedish. This study mainly focuses on the automatic evaluation of mispronunciations at a phonetic level. We describe a new database we have collected for this work. Then we report the reliability of several phonetic scores to locate automatically segmental problems in student utterances.
