Method and apparatus for recognizing previously unrecognized speech by requesting a predicted-category-related domain-dictionary-linking word
First Claim
1. A voice communication method comprising 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 said 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.

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.

11. A speech communication apparatus comprising:
-
input means for inputting speech into said apparatus; recognizing means for recognizing the speech input by said input means using a first dictionary; predicting means for predicting the category of an unrecognized word included in the input speech based on the recognition of the input speech by said recognizing means; outputting means for outputting a question to be asked of 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 means for re-recognizing the unrecognized word with the second dictionary specified in response to the word inputted by the operator. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A computer program product comprising a computer usable medium having computer readable program code means embodied in said medium for enabling speech communication by a computer, said computer program product comprising:
-
first computer readable program code means for causing said computer to input speech thereinto; second computer readable program code means for causing said computer to recognize the input speech using a first dictionary; third computer readable program code means for causing said computer to predict the category of an unrecognized word included in the input speech based on the recognition of the input speech caused by said second computer readable program code means; fourth computer readable program code means for causing said computer to output a question to be asked of 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 fifth computer readable program code means for causing said computer to re-recognize the unrecognized word with the second dictionary specified in response to the word inputted by the operator. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
