Book Search Apparatus for Metathesis Training via Phonetic Pattern Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for searching books to help reduce metathesis in children's speech are ineffective as they do not provide a method to efficiently find books that can aid in this specific training.
Innovation Solution
A book search apparatus that includes a database storing information on book titles and the frequency of mora character notation pairs appearing in forward order, allowing users to input correctly and incorrectly pronounced phrases to find books that can help reduce metathesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a general book search method is used to find books for children, then books with pictures favored by children can be found, but it is not possible to efficiently find books specifically for training to reduce metathesis
Solution Approach 1:
The patent changes the search parameters from general picture preferences to specific phonetic patterns. The search system analyzes metathesis error patterns (swapped syllables) and searches for books containing the correct phonetic sequences, transforming the search from visual preference-based to phonetic pattern-based selection.
Solution Approach 2:
The patent introduces a phonetic analysis intermediary that processes the relationship between metathesis errors and book content. This intermediary analyzes the swapped syllable patterns and matches them with correct phonetic sequences in books, serving as a bridge between the error pattern and appropriate training materials.
2Ease of operation
If books are selected based on picture preferences, then children are motivated to read, but the books may not address specific speech errors like metathesis
Solution Approach 1:
The patent segments the book selection process into two independent dimensions: visual appeal (pictures) and phonetic training value (correct phonetic patterns). By separating these criteria, the system can independently optimize for both child motivation and training effectiveness without compromising either aspect.
3Measurement precision
If a comprehensive analysis of all books is performed to find those effective for metathesis training, then accurate training materials can be identified, but the search process becomes complex and time-consuming
Solution Approach 1:
The patent extracts only the essential phonetic pattern information from books - specifically the sequences of syllables that correspond to metathesis errors. By extracting and storing only these critical phonetic patterns rather than analyzing entire book contents, the system achieves high precision in identifying training books while keeping the search mechanism relatively simple.

AI summary
Provided is an invention for efficiently searching for books used in training to reduce metathesis. A book search database storage unit 110 stores a book search database in which information identifying a book, information regarding a frequency of a proximity number for a mora character notation pair appearing in forward order in the book, and information regarding a frequency of a proximity number for the mora character notation pair appearing in reverse order are associated with each other. A display unit 300 displays a book search screen including a correctly pronounced phrase input region and an incorrectly pronounced phrase input region. A subject pronunciation designation unit 120 determines two mora character notations and a proximity number to use as search conditions based on an input of the correctly pronounced phrase input region and an input of the incorrectly pronounced phrase input region. A subject book information generation unit 130 generates search results including information regarding books matching the search conditions from the book search database.
