Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional word pronunciation learning devices fail to effectively identify and target specific combinations of consecutive pronunciation components where users struggle, limiting personalized and efficient learning.
Innovation Solution
An electronic device with a processor and memory that evaluates user pronunciation of words for each combination of consecutive pronunciation components, outputs learning information based on the evaluation, and provides targeted advice and word lists for improvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional pronunciation learning devices evaluate user pronunciation only at the word level, then the evaluation process is simple, but the precision of identifying specific pronunciation weaknesses is insufficient
Solution Approach 1:
The patent segments pronunciation evaluation from the word level to the phoneme level. Instead of evaluating entire words as single units, the system breaks down words into individual pronunciation components (phonemes) and evaluates each phoneme separately. This segmentation enables precise identification of which specific phonemes users struggle with, transforming the evaluation from a coarse word-level assessment to a fine-grained phoneme-level analysis.
Solution Approach 2:
The patent applies local quality by providing customized learning content targeted at specific phoneme weaknesses rather than generic word-level practice. The system identifies which particular phonemes (local components) a user struggles with and generates learning materials specifically for those phonemes, rather than requiring users to practice entire words uniformly. This localized approach optimizes learning efficiency by focusing practice on specific weak areas.
2Adaptability or versatility
If pronunciation learning provides generic word lists for practice, then the learning material is easy to generate, but the adaptability to individual user weaknesses is limited
Solution Approach 1:
The patent implements dynamics by making learning material generation adaptive and dynamic based on real-time evaluation results. Instead of providing static, pre-defined word lists, the system dynamically generates customized learning materials by selecting words that contain the specific phonemes identified as weak points during evaluation. This dynamic adaptation ensures learning content evolves with the user's progress and continuously targets current weaknesses.
Solution Approach 2:
The patent applies feedback by using evaluation results to inform and adjust learning material generation. The system evaluates user pronunciation performance on specific phonemes, then uses this feedback to automatically generate or select appropriate learning words that target those weak phonemes. This closed-loop feedback mechanism ensures learning materials are continuously optimized based on actual user performance data.

AI summary
Pronunciation learning processing is performed, in which evaluation scores on pronunciation for respective words are acquired from a pronunciation test that uses multiple words, the acquired evaluation scores are summated for each combination of consecutive pronunciation components in the words, and learning information based on the result of summation is output.
