Multilingual AI Speech Therapy With Adaptive Error Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional speech therapy for aphasia and related speech impairments requires frequent clinical visits and relies heavily on external reinforcement, limiting accessibility and personalization, and does not facilitate ongoing, self-monitored, adaptive therapy outside of a clinical setting.
Innovation Solution
A computer-implemented method for adaptive, multilingual speech therapy using a multilingual language identification model, language-specific recognition, and a speech and language error matrix to dynamically adjust therapy tasks based on real-time analysis of patient speech and engagement metrics, enabling personalized treatment across diverse linguistic contexts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional speech therapy with speech-language pathologist is used, then speech therapy effectiveness is improved through external feedback and modeling, but accessibility and frequency of therapy sessions deteriorate due to requirement of frequent clinical visits and specialized providers
Solution Approach 1:
The system enables patients to perform self-monitored speech therapy exercises using automated feedback mechanisms. The AI agent provides real-time monitoring and correction without requiring a speech-language pathologist's direct involvement, allowing patients to conduct therapy independently at home or other settings.
Solution Approach 2:
The system implements automated feedback loops where the AI agent analyzes patient speech responses, provides real-time corrections and modeling, and adjusts therapy based on performance. This replaces manual feedback from speech-language pathologists with automated acoustic and linguistic analysis.
2Reliability
If traditional speech therapy with manual assessment is used, then real-time external feedback is provided by speech-language pathologist, but ability for ongoing training and iterative speech improvement outside of clinic deteriorates
Solution Approach 1:
The system implements automated feedback loops where the AI agent analyzes patient speech responses, provides real-time corrections and modeling, and adjusts therapy based on performance. This replaces manual feedback from speech-language pathologists with automated acoustic and linguistic analysis.
Solution Approach 2:
The system enables continuous therapy sessions to be conducted outside the clinic without interruption. Patients can engage in repeated practice exercises with immediate automated feedback, allowing iterative improvement to continue indefinitely rather than being limited to scheduled clinic appointments.
3Ease of manufacture
If standardized speech therapy exercises are used, then therapy structure and guidance are maintained, but personalization and adaptation to individual patient progress deteriorate
Solution Approach 1:
The system dynamically adjusts therapy exercises and difficulty levels based on real-time analysis of patient performance. The AI agent modifies task complexity, provides targeted feedback on specific error types, and adapts the therapy curriculum to match individual patient progress, transforming static exercise protocols into adaptive learning pathways.
Solution Approach 2:
The system changes therapy parameters such as exercise difficulty, response time requirements, and feedback intensity based on patient performance metrics. The AI agent analyzes speech accuracy, fluency, and error patterns to automatically adjust therapy parameters, providing personalization without requiring manual intervention.
4Reliability
If frequent clinical visits for speech therapy are required, then ongoing monitoring and correction are ensured, but loss of time and logistical burden increase for patients
Solution Approach 1:
The system enables patients to perform self-monitored speech therapy exercises using automated feedback mechanisms. The AI agent provides real-time monitoring and correction without requiring a speech-language pathologist's direct involvement, allowing patients to conduct therapy independently at home or other settings.
Solution Approach 2:
The AI agent serves as an intermediary between the patient and the therapy process, providing automated monitoring and feedback that previously required direct clinician involvement. This intermediary enables continuous therapy without the logistical constraints of scheduling and traveling to clinical appointments.

AI summary
A method for treating a language disorder in a patient includes receiving therapist input specifying a speech target and engagement indicator priority, capturing audio of a speech response to a therapy prompt, and identifying the language of the response using a multilingual language identification model. The method further comprises analyzing the speech response with a language-specific recognition model to extract speech features and classify errors across multiple linguistic and acoustic dimensions. Engagement indicators are extracted and used to compute an engagement score, which, along with the error classifications and speech target, informs a decision model that selects a therapy task. The selected task is presented to the patient, and a subsequent speech response is captured to update error classifications. The decision model is iteratively refined based on therapist input and revised error data, enabling adaptive, personalized therapy progression.
