About Spoken Letter

A voice they love, every night. Spoken Letter turns a real family voice recording into a personal story your child can play on their Yoto — screen-free, parent-approved, and made to be heard again and again. Grandparents and relatives record or upload a memory, Gemini helps shape it into a child-friendly story kept in their own real voice (no cloning), you review it, and it exports as a Yoto-ready story. Launch offer: 2 stories for €2.99 — buy 1, get 1 free.
