Claim:
1. A method comprising: receiving a first language model for a first domain having a first training set, wherein the first language model is used in a spoken dialog application; identifying a second language model for a second domain, wherein the second language model is smaller than the first language model; selectively sampling training data from the second language model, to yield selectively sampled training data; concatenating, via a processor, the first language model by replacing a portion of the first training set in the first language model with the selectively sampled training data, to yield a concatenated first language model; replacing the first language model with the concatenated first language model for use in the spoken dialog application; and receiving audible speech from a user via the spoken dialog application; and converting, via the spoken dialog application, the audible speech into text via the concatenated first language model.
