LANGUAGE MODEL TRAINING METHOD AND APPARATUS, AND SPEECH RECOGNITION METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a language model training method and apparatus for training a neural network based language model, and a speech recognition method and apparatus for recognizing speech data on the basis of a trained language model.SOLUTION: A language model training apparatus according to one embodiment may convert input training data into error-containing training data, and train a neural network based language model on the basis of the error-containing training data. A speech recognition apparatus recognizes speech data using the trained language model, and outputs a recognition result of the speech data.SELECTED DRAWING: Figure 1
