In interactive speech applications the expected vocabulary and the expected user utterances change from one dialogue step to the next one. The use of several context dependent language models results in a better system performance than the use of a single model. In this paper we present a new approach combining syntactical and statistical language constraints to a single language model. Recognition results on a database of spelled city names are presented. Furthermore a match against the list of all possible city names is performed.
