Abstract
The results show that the possibilistic models provide significantly lower word error rate on the specialized domain task, where classical n-gram models fail due to the lack of training materials. For the broadcast news, the probabilistic models remain better than the possibilistic ones. However, a log-linear combination of the two kinds of models outperforms all the models used individually, which indicates that possibilistic models bring information that is not modeled by probabilistic ones.
