Mobile Speech Therapy Feedback Loops for At-Home Aphasia Practice
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional speech therapy for aphasia and related speech impairments requires frequent clinical visits and external reinforcement, making it inaccessible to individuals with logistical, financial, or geographic barriers, and does not facilitate ongoing, independent, and adaptive speech improvement outside of a clinical setting.
Innovation Solution
A system and method for recursive self-feedback (RSF)-based speech therapy using a mobile device that provides adaptive, data-driven feedback, allowing users to engage in iterative speech improvement through recursive self-monitoring and feedback loops, adjusting therapy difficulty levels based on user performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional speech therapy with external reinforcement is used, then speech accuracy can be improved through pathologist feedback, but accessibility and independence deteriorate due to frequent clinical visits and external dependency
Solution Approach 1:
The system enables patients to independently perform speech therapy exercises using their mobile devices, with automated feedback replacing the need for frequent pathologist visits. The self-service nature allows patients to conduct therapy at home, improving accessibility while maintaining speech accuracy through automated monitoring and feedback mechanisms.
Solution Approach 2:
The system implements automated feedback loops where the mobile device records patient speech, analyzes accuracy against target phrases, and provides immediate corrective feedback. This automated feedback system maintains speech accuracy improvement while eliminating the need for external reinforcement from pathologists during each exercise session.
2Measurement precision
If traditional speech therapy with external reinforcement is used, then speech accuracy can be improved through pathologist feedback, but therapy continuity deteriorates due to logistical and financial barriers
Solution Approach 1:
By transferring therapy execution to the patient's mobile device, the system enables continuous therapy sessions at home without interruption by logistical barriers. The self-service model allows unlimited access to therapy exercises, ensuring long-term continuity while maintaining accuracy through automated feedback.
Solution Approach 2:
The system pre-loads therapy programs and target phrases onto the mobile device, enabling patients to perform therapy exercises anytime without needing to schedule or travel to clinical appointments. This preliminary preparation ensures uninterrupted therapy continuity while maintaining speech accuracy through pre-programmed feedback criteria.
3Ease of operation
If automated feedback systems are implemented, then accessibility and independence can be improved, but feedback quality deteriorates without expert pathologist involvement
Solution Approach 1:
The system replaces the mechanical system of manual pathologist feedback with automated speech recognition and analysis algorithms. The mobile device's processor and software automatically analyze speech accuracy, phoneme recognition, and fluency metrics, providing expert-level feedback quality without requiring actual pathologist involvement in each session.
Solution Approach 2:
The system introduces an intermediary layer of automated speech processing technology between the patient and the pathologist. This intermediary analyzes speech patterns, compares them against target phrases, and generates feedback, thereby maintaining feedback quality while enabling patient independence and accessibility.
4Measurement precision
If frequent clinical visits are required, then speech accuracy can be monitored in real-time, but time and resource efficiency deteriorate
Solution Approach 1:
The system implements real-time feedback loops using the mobile device's microphone and processor to immediately analyze speech accuracy as the patient speaks. This automated real-time monitoring provides continuous accuracy assessment without requiring pathologist presence, thereby maintaining measurement precision while eliminating time loss associated with scheduling and attending frequent clinical visits.

AI summary
Systems and methods are provided for generating, managing, adapting, and delivering speech therapy to a user via a mobile device in an at-home or out-of-clinic setting. Users may be persons experiencing aphasia or other speech conditions. For example, prompts may be communicated to a user, and their spoken responses recorded and analyzed. Based on analysis of the responses, these systems and methods may determine a mode of response including but not limited to playback of the user's spoken response to allow the user to recursively self-assess and/or self-correct. User performance and improvement trends may be assessed, and utilized to adapt future therapy sessions.
