The aim of this work is to integrate segments of words into a category-based Language Model. Two proposals of this kind of models are presented. On the other hand an interpolation of a category-based model with a classical word-based Language Model is studied as well. The models were integrated into an ASR system and evaluated in terms of WER. Experiments on a spontaneous dialogue corpus in Spanish are reported. These experiments show that integrating word segments in a category-based Language Model, a better performance of the model can be achieved.
