SimuSpeech: an AI-powered platform for public speaking practice
Helping users build confidence through real-time audience simulation and feedback.
Project Overview
Public speaking is one of the most common forms of social anxiety, especially among college students.
This project explored public speaking anxiety through deep-listening interviews and psychological research, then used Kano Model analysis (78 participants) to prioritize UX prototype concepts. The design was evaluated through remote usability testing and SUS surveys (4 participants).
Key Research Questions
- Why do higher-education students experience public speaking anxiety? - Which concepts should be prioritized for development and testing?

Using Kano Model Analysis to prioritize eight conceptual features for prototyping.

Kano-style survey
I conducted a Kano-style survey via Amazon Mechanical Turk (n=78) to evaluate eight conceptual features. Each feature was assessed using functional and dysfunctional questions, and an importance rating.

Kano Model Analysis results
Next, I analyzed valid responses using Kano Model Analysis to inform decisions on which features to prototype and test.
Evaluating the flow prototype through remote task-based usability testing.
This evaluation captured behavioral performance (task completion), perceived usability (SUS), and qualitative feedback (think-aloud) to understand both what happened and why.
Remote task-based usability testing
I conducted remote task-based usability testing on Loop11 to evaluate whether participants could successfully complete task and identify usability issues.

System Usability Scale (SUS)
After participants complete their task, they were asked to fill the System Usability Scale (SUS) survey to assess overall perceived usability.
