Express Publishing scales ELT audio production across 90+ countries with Wondercraft AI voice tools

The problem

Express Publishing's audio production relied on freelance voice actors and in-studio sessions, making it hard to scale or turn around updates quickly. Last-minute changes required waiting days to rebook talent, especially for children's voice projects.
