The interactive version of the story that’s being promoted online unfolds in fairy tale-like fashion, but with a small twist. Readers have to speak the words aloud into a microphone to keep the story going, and help Goldivox find her voice.

“Goldivox is one part fairy tale we all know and one part a story that many of us never imagined,” said Rupal Patel, a speech scientist and founder of VocaliD. “As we understand Goldivox’s need to find a voice that fits, we discover that each one of us has the power to share voice.”

The marketing push—created by Saatchi & Saatchi, New York—encourages people to lend their voices to a crowdsourced project called the Human Voicebank, which records human voices. Contributors read a series of short phrases and sentences aloud, which contain all the sounds and sound combinations in the language they speak. The recordings are then used to convert text into personalized, digital voices on text-to-speech devices that people with voicelessness rely on to communicate.

In the last year, more than 12,000 people from 110 countries contributed more than 4.57 million sentences on the online platform, the company said.
