Which language model to use for dictation

Question

I intend to use the sphinx4 in dictation mode but I have a question about the language model. My application will have a very large vocabulary, ie, it can use all the English words and I do not know which will be the phrases that will be said. So which model language should I use? Sphinx4 have any specific language model for these cases?
