I developed the visual identity and launch experience for Voice Builder, a custom voice creation tool powered by Supertone’s Supertonic 2, one of the fastest on-device TTS models.

The visual concept was built around two core ideas: speed and individuality. To express Supertonic 2’s high-speed performance, I introduced a vivid yellow lightning symbol as a key graphic motif, turning the product’s technical advantage into an immediate visual cue.

At the same time, I explored how the unique characteristics of each voice could be translated into a visual identity. I created a library of 120 ASCII-art voice cards, with a different card randomly assigned each time a new custom voice is generated. The system gives every voice its own visual character while reflecting the computational and technical nature of the product.

This visual language was extended across the website, key visuals, launch graphics, and product introduction film, creating a cohesive experience that communicates both the performance of the technology and the creative potential of building a voice of your own.
