Since we cannot exclude that speech recognizers fail sometimes, it is important to examine how users react to recognition errors. In correction situations, speaking style becomes more accentuated to disambiguate the original mistake. We examine the effect of speaking style in such situations on speech recognition performance. Our results indicate that hyperarticulated effects occur in correction situations and decrease word accuracy significantly.
