Phoneme-Level Speech Evaluation for Pronunciation Progress Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Healthcare and educational providers face inefficiencies in tracking patient progress and administrative tasks due to outdated technologies that lack detailed analysis of speech pronunciation and require significant time for manual documentation, leading to suboptimal use of therapeutic sessions.
Innovation Solution
A computer-implemented system for evaluating word structures in audio recordings, including phoneme-level transcription, diarization, and analysis to score pronunciation accuracy, generate documentation, track progress, and recommend future sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If simple speech-to-text transcription technology is used, then the basic transcription function is achieved, but the ability to analyze phoneme-level pronunciation accuracy and position is lost
Solution Approach 1:
The system segments speech analysis into multiple hierarchical levels: phoneme detection, sound identification, position determination (initial, middle, final), and pronunciation accuracy scoring. This segmentation enables detailed phoneme-level analysis while managing system complexity through modular processing components.
Solution Approach 2:
The patent introduces an intermediary processing layer between simple transcription and comprehensive analysis. This layer includes phoneme detection algorithms, sound classification modules, and position identification components that bridge the gap between basic text transcription and detailed pronunciation evaluation.
2Reliability
If manual documentation and progress tracking are performed, then comprehensive patient records are created, but significant time is consumed reducing productivity
Solution Approach 1:
The system enables automated self-service documentation by processing audio recordings through transcription, phoneme analysis, and progress tracking algorithms. The system automatically generates comprehensive patient records, performance scores, and progress reports without requiring manual provider input, thereby maintaining reliability while significantly improving productivity.
Solution Approach 2:
The system performs preliminary analysis of speech patterns, phoneme accuracy, and position correctness during and immediately after therapy sessions. This preliminary action prepares structured data and draft documentation in advance, reducing the time required for subsequent manual review and finalizing records.
3Measurement precision
If detailed phoneme-level analysis is implemented, then pronunciation accuracy can be scored, but processing time and computational resources increase
Solution Approach 1:
The system implements partial analysis by focusing on specific phonemes, sounds, and word positions relevant to the patient's therapy goals rather than analyzing every aspect of speech equally. This selective approach maintains high scoring accuracy for targeted elements while reducing overall processing time and computational resources.
Solution Approach 2:
The analysis is performed periodically at key intervals: during therapy sessions for real-time feedback, immediately after sessions for detailed scoring, and at scheduled intervals for progress tracking. This periodic action structure balances detailed analysis requirements with efficient resource utilization.
Data Source
AI summary
Systems, apparatuses, and methods for evaluating word structures in audio recordings are disclosed. Speech from one or more speakers may be recorded to create an audio file. The audio file may be transcribed to generate a transcript that identifies one or more words in the speech. One or more phonemes may be detected in the one or more words in the speech. The audio file may be isolated into one or more audio fragments that correspond to the one or more phonemes. The one or more audio fragments may be analyzed to determine whether the one or more phonemes in the one or more words was pronounced correctly or incorrectly in the corresponding sound-based unit in the position in the one or more words. Performance of the speech may be scored by calculating correct and incorrect pronunciations of the one or more phonemes.
