A stroke strikes every 40 seconds.
Inspired by my father's experience, I designed COSMOS — a speech therapy app empowering stroke survivors to reclaim their voice.

PROJECT OVERVIEW
PROBLEM
40% of stroke survivors have speech disabilities
Stroke survivors face a critical gap in accessible, personalized speech therapy resources. Current solutions fall short, hindering recovery and life quality.
TARGET USERS
Stroke survivors with speech difficulties. Adaptable for individuals with speech impairments from various neurological conditions.
A gamified, voice shadowing exercise that helps users with incremental practices and boosts motivation for recovery
Daily Voice Shadowing
Voice shadowing with audio guides and AI-powered mistake detection.
Mistake Review
Compare your speech to high-quality audio examples to improve your pronunciation and delivery.
Gamified Rewards
Earn points for completed exercises, redeemable for rehabilitation-aiding products.
RESEARCH - UNDERSTANDING THE PROBLEM SPACE
USER INTERVIEW
To understand the challenges faced by stroke survivors, I conducted interviews with 12 people from three key user groups:
QUANTITATIVE DATA
I conducted 20+ surveys on stroke communities and synthesized findings from the surveys and the user interviews to identify the pain points and needs of each user group, leading to the best solution.
Stroke Survivors
Post-stroke Struggles:
Cost of Therapy
The demand for rehab therapists far exceeds supply, driving up costs.
Family Caregivers
Time Sacrifices
Family caregivers avoid hiring help due to trust, opting to devote their own time instead.
Medical Professionals
Importance of Voice Shadowing
Medical experts say voice shadowing, with correction of mistakes, is the best method for speech therapy.
COMPETITIVE AUDIT
I conducted competitive analysis to evaluate existing speech apps - for potential features and to identify market gaps:
Product
Speech-impaired Focused
Subscription Model
Voice Recognition
Accessibility Features
Personalized Content
High Affordances
Multiple Languages
Gamified Tasks
Recording Features
Most language apps are for general learnings, not specifically for stroke survivors
Lack of extensive, detailed personalization in available solutions
RESEARCH INSIGHTS
Dependance on caregivers

IDEATION
HMW
(How Might We)
design a voice-activated platform that seamlessly integrates speech therapy into the daily routines of stroke survivors, ensuring consistent and repetitive practice?
LOW-FI PROTOTYPES
I sketched and evaluated four gamified, voice-activated concepts to solve the design challenge: motivating stroke survivors' daily speech practice.
IMPLEMENTING FEEDBACK
Voice Shadowing Audio Guide Options
To further develop my core feature - Daily Voice Shadowing, I conducted a second round of user testing and evaluated multiple options to determine the most effective audio guide.
