Voice Recognition Candidate Selection with Matching Numerals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In voice recognition systems, it is difficult to determine whether a numeral spoken by a user refers to a candidate number or a street number, leading to false recognition when candidate numbers are assigned to targets displayed in list form, especially when character strings representing numerals are used.
Innovation Solution
The system associates target candidates with candidate numbers such that numerals of the candidates coincide with numerals of the numbers, allowing correct voice recognition by eliminating the need to differentiate between the two, and displays them in a coordinated list format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If candidate numbers are assigned sequentially to target candidates displayed in list form, then the system enables voice recognition selection of targets, but false recognition occurs when target candidates are numerals that do not coincide with their candidate numbers
Solution Approach 1:
The patent changes the parameter of candidate number assignment from sequential ordering to matching the numerical value of the target candidate itself. When a target candidate is a numeral, its candidate number is set to match that numeral, creating coincidence between the displayed number and the candidate number. This parameter change eliminates the ambiguity that caused false recognition while preserving voice recognition functionality.
2Ease of operation
If the system allows selection by saying either target candidate or candidate number, then user convenience is improved, but the system cannot determine whether a spoken numeral refers to a candidate number or a street number
Solution Approach 1:
The patent merges the candidate number with the target candidate's own numeral when they coincide. By setting the candidate number to match the target candidate's numeral value, the system creates a unified identifier that eliminates the need to distinguish between candidate number and target value. This merging allows the voice recognition system to correctly identify the intent without additional complexity.

AI summary
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.
