Abstract

A candidate selection apparatus utilizing voice recognition includes an association unit that associates target candidates with candidate numbers so that numerals of the target candidates coincide with numerals of the candidate numbers when the target candidates to be displayed in list form are character strings representing the numerals of the candidate numbers, and a display control unit that displays the target candidates and the candidate numbers in list form in accordance with the associations made between the target candidates and the candidate numbers.

Claims

1. A candidate selection apparatus utilizing voice recognition that enables selection of a target candidate from a plurality of target candidates displayed in a numbered list form by performing voice recognition of either the selected target candidate or a candidate number of the numbered list assigned to the selected target candidate, spoken by a user from among target candidates and candidate numbers that are displayed in list form, the candidate selection apparatus comprising:

a character string determination unit that determines whether or not a character string of a target candidate to be displayed in a numbered list represents a numeral that is the same as a candidate number of the list, where the target candidates to be displayed in the list represent choices available for selection by the user, and the candidate numbers are the numerals of the numbered list;

an association unit that associates target candidates with the candidate numbers of the numbered list so that numerals of the target candidates are the same as the numerals of the candidate numbers when the character string determination unit determines that a character string of a target candidate to be displayed in the numbered list represents the numeral of a candidate number of the list;

a display control unit that displays the target candidates and the candidate numbers associated with each other by the association unit in list form in accordance with associations made between the target candidates and the candidate numbers of the list; and

a voice recognition unit that performs voice recognition of the target candidate or the candidate number spoken by the user from among the target candidates and the candidate numbers that are displayed in list form by the display control unit, whereby a spoken target candidate recognized by the voice recognition unit or a target candidate associated with a spoken candidate number recognized by the voice recognition unit is selected by the candidate selection apparatus from among the target candidates displayed in list form.

2. The candidate selection apparatus utilizing voice recognition according to claim 1, wherein, when there is no target candidate corresponding to a character string representing a numeral of a candidate number, the association unit does not associate the candidate number corresponding to the numeral with any target candidate, and associates only a target candidate corresponding to a character string representing a numeral coinciding with a numeral of a candidate number with the candidate number whose numeral coincides with the numeral.

3. The candidate selection apparatus utilizing voice recognition according to claim 1, wherein, when there is no target candidate corresponding to a character string representing a numeral of a candidate number, the association unit associates the candidate number corresponding to the numeral with a target candidate corresponding to a character string representing a numeral other than the numeral of the candidate number.

4. The candidate selection apparatus utilizing voice recognition according to claim 1, wherein the target candidates corresponding to the character strings representing the numerals of the candidate numbers include a street number, block number, or house number.

5. A candidate selection method utilizing voice recognition that enables selection of a target candidate from a plurality of target candidates displayed in a numbered list form by performing voice recognition of either the selected target candidate or a candidate number of the numbered list assigned to the selected target candidate, spoken by a user from among target candidates and candidate numbers that are displayed in list form, the candidate selection method comprising:

a first step of, with a character string determination unit comprising a computer, determining whether or not a character string of a target candidate to be displayed in a numbered list represents a numeral that is the same as a candidate number of the list, where the target candidates to be displayed in the list represent choices available for selection by the user, and the candidate numbers are the numerals of the numbered list;

a second step of, with an association unit comprising a computer, associating target candidates with the candidate numbers of the numbered list so that numerals of the target candidates are the same as the numerals of the candidate numbers when the character string determination unit determines that a character string of a target candidate to be displayed in the numbered list represents the numeral of a candidate number of the list;

a third step of, with a display control unit comprising a computer, displaying the target candidates and the candidate numbers associated with each other by the association unit in list form in accordance with associations made between the target candidates and the candidate numbers of the list; and

a fourth step of, with a voice recognition unit comprising a computer, performing voice recognition of the target candidate or the candidate number spoken by the user from among the target candidates and the candidate numbers that are displayed in list form by the display control unit, whereby a spoken target candidate recognized by the voice recognition unit or a target candidate associated with a spoken candidate number recognized by the voice recognition unit is selected by the candidate selection apparatus from among the target candidates displayed in list form.

6. A candidate selection method utilizing voice recognition according to claim 5, wherein, when there is no target candidate corresponding to a character string representing a numeral of a candidate number, the association unit does not associate the candidate number corresponding to the numeral with any target candidate, and associates only a target candidate corresponding to a character string representing a numeral coinciding with a numeral of a candidate number with the candidate number whose numeral coincides with the numeral.

7. A candidate selection method utilizing voice recognition according to claim 5, wherein, when there is no target candidate corresponding to a character string representing a numeral of a candidate number, the association unit associates the candidate number corresponding to the numeral with a target candidate corresponding to a character string representing a numeral other than the numeral of the candidate number.

8. A candidate selection method utilizing voice recognition according to claim 5, wherein the target candidates corresponding to the character strings representing the numerals of the candidate numbers include a street number, block number, or house number.
