ABSTRACT:
A voice communication method includes the steps of inputting speech into an apparatus, recognizing the input speech using a first dictionary, predicting the category of an unrecognized word included in the input speech based on the recognition of the input speech in the recognition step, outputting a question to be asked to an operator requesting the operator to input a word which is included in the first dictionary and which can specify a second dictionary for recognizing the unrecognized word, based on the predicted category, and re-recognizing the unrecognized word with the second dictionary specified in response to the word inputted by the operator. The invention also relates to an apparatus performing these functions and to a computer program product instructing a computer to perform these functions.
