Abstract
A language model learning system for learning a language model on an identifiable basis relating to a word error rate used in speech recognition. The language model learning system () includes a recognizing device () for recognizing an input speech by using a sound model and a language model and outputting the recognized word sequence as the recognition result, a reliability degree computing device () for computing the degree of reliability of the word sequence, and a language model parameter updating device () for updating the parameters of the language model by using the degree of reliability. The language model parameter updating device updates the parameters of the language model to heighten the degree of reliability of the word sequence the computed degree of reliability of which is low when the recognizing device recognizes by using the updated language model and the reliability degree computing device computes the degree of reliability.
