Eunoia was my final year project: an app that delivers immediate emotional support through speech and text for people who cannot reach professional help in the moment.
Most chatbots read words. Eunoia also listens to tone. Speech emotion recognition classifies how the user sounds, and that signal shapes both the content and the synthesized voice of the response.
A conversation turn
- 01User speaks or types
- 02Emotion recognized from voice and text
- 03Response generated for that emotional state
- 04Spoken back with matching tone
Designing for someone having a bad day
The interface had one rule: never add friction to a person who is already struggling. One tap to talk, large calm surfaces, no streaks or gamification, and conversation history that reads like a journal rather than a chat log.
The hardest design work was tone calibration: an empathetic response that arrives too cheerful is worse than none. We tuned response style against emotion classes rather than shipping one voice for every state.
