Abstract
A method, a system, and a computer program product for building an n-gram language model for an automatic speech recognition. The method includes reading training text data and additional text data both for the n-gram language model from a storage, and building the n-gram language model by a smoothing algorithm having discount parameters for n-gram counts. The additional text data includes plural sentences having at least one target keyword. Each discount parameter for each target keyword is tuned using development data which are different from the additional text data so that a predetermined balance between precision and recall is achieved.
