Record a short sample once. From then on, every story in the library can play back in your voice — chosen by your child, on the night, whether or not you are in the room.
Recording yourself reading a specific book gives you one recording of one book — and children always want a different one. A voice profile works differently: read a short passage once, and the app can narrate anything in the library in your voice. Your child picks the story, not you.
Read the passage on screen in a quiet room, at your normal reading pace. The app checks the recording is clear enough before building the profile, so you know straight away whether it worked rather than discovering it three stories later.
Your recording builds your voice profile and nothing else. It is never shared, never used to train anyone's general models, and you can delete it — recording and voice model together — from the profiles screen at any time.
Mum, Dad, a grandparent, an older sibling. Each family member records their own profile, and your child chooses whose voice reads tonight's story.
