Color My Voice is an engaging mobile web app that translates human speech into beautiful, frameable sound-art posters based on the historical pitch-color associations of classical composer Nikolai Rimsky-Korsakov, a reknowned synesthete.

While roughly 4% of the world experiences synesthesia (blended senses), researchers lack large, diverse datasets to study it. Our app solves this by turning clinical voice collection into a fun, zero-friction creative experience. With explicit consent, it securely crowdsources anonymized, numerical voice summaries into a local research database—giving scientists the global data scale they need while keeping participant data completely private.
