APPARATUS AND METHOD FOR ADAPTING LANGUAGE MODEL BASED ON DOCUMENT CLUSTERING

摘要

The present invention relates to a kind of device and a kind of method,For adjusting the language model of clustering documents. The device includes: grouped element to the entire corpus of documents group of cluster and at least one cluster, so that the similar field of document can be grouped for adjusting language model according to the method for the present invention; A kind of voice recognition unit executes speech recognition to generate for inputting voice, speech recognition result word grid; Cluster selector calculates distance value to center, while from the result and cluster of speech recognition, and selects at least one similitude clustering, is based on calculated distance value; One weight calculation unit, at least one the similar cluster for calculating weighting language model are based at least one similitude clustering of distance value; Language model interpolation unit generates interpolation language model and is based on weight and language model; Pass through interpolation language model to the word grid that the most note that resets scores is cut with the unit that resets scores. ;The 2014 of copyright KIPO submissions
