The Campaign

Each voice is completely unique to that person in the world, which explains how voiceprint authentication works. And this is why the voice is the best means of expressing a person’s individuality and conveying emotions to others. The idea we came up with to reacquaint people with voice communications was to transform voices into something that looks beautiful to the eye and can be given to loved ones.

Creative Execution

First, we measured the vibrations of voices and turned them into visible Chladni figures. Using 3D modeling, we transformed the Chladni figures into chocolate molds. Working in collaboration with Mont St Clair, the most famous patisserie in Japan, we sold the chocolates as Voice Chocolates that let women give their voices, transformed into chocolate, to the men they love for Valentine’s Day. The chocolates were delivered to the recipients on Valentine’s Day. By scanning the chocolate with a special app that recognized AR markers in the chocolate, the recipient could play back a voice message from his Valentine on his smartphone.

Indication of how successful the outcome was in the market

The expected number of Voice Chocolates quickly sold out. Many different chocolates were made with original designs based on voices captured with the app. The world’s first beautiful voice communications were completed by sending the beautifully formed chocolates to loved ones. In this way, we successfully designed a new form of voice communication.

It’s a Valentine’s Day custom in Japan for almost women to give chocolates and to tell their feelings to men. Japanese people are too shy and they don’t often express their love to the others, but Valentine’s Day is exceptional. The strategy to remind people of the wonder of communicating by voice was for Docomo, Japan’s largest mobile phone company, to market a service letting women give to the men they love beautifully formed chocolate that visualized their Valentine’s message.
