Add narration and music
Record yourself reading the book, import audio, generate narration, and add background music that ducks under the voice.
Free Free on every plan
Open a page and find the sound control
Narration belongs to a single page. Open the page editor and tap the sound control.Record your own voice
Tap record and read the page. Stop when you are done. You can preview the recording, set its narration volume for that page, or remove it and record again.
There is no trimming or fading — if a take is wrong, re-record the page. It takes fifteen seconds and is less fiddly than editing on a phone.
This is free, unlimited, and needs no internet.
Tip. Record all your pages in one sitting, in a quiet room, holding the phone about a hand’s width away. Consistency across pages matters more than perfection on any one.
Or import an audio file
MP3, M4A, WAV, and AAC are accepted everywhere, and Android also takes OGG. Useful if you recorded on better equipment, or if a grandparent sent you a recording.Or generate narration (Studio Plus)
Where AI narration is available, you can have the app read your text in one of several curated voices. Review the words, voice, style, and credit cost before creating it. The result is attached to the page; preview it from the Sound screen, or remove it and create another.
This costs 3 credits per page and is capped at about 2,000 characters.
Check the page timing
On a page with a still photo, Auto holds the picture on screen until your narration finishes. Your recording is never cut short.
If you want a page to linger even when the words are short, set a minimum display time instead — the page then holds for at least that long.
Tip. Leave it on Auto unless a particular page needs a pause. It is the setting that makes a read-aloud book feel unhurried.
Add story music
Music belongs to the whole project, not a page. In project settings, pick one of the six included tracks, reuse audio from your Library, or import your own file. Preview it and set its volume. It loops across the finished export.Tip. The included tracks are labelled by mood and work offline, so they are the quickest way to get music under a book without hunting for a file you have the rights to.
Turn on Lower music under narration
One switch. When a page has narration, the music level drops so the voice stays clear. Leave it on unless you have a reason not to.Export and check
Export the video and listen to the whole thing once before sending it to anyone. See export a PDF or video.
A word about which narration to use
Generated narration is convenient and it sounds fine. But for a book your child will still have in twenty years, your own voice is worth the extra ten minutes. The technology is not the point of the object.
Use generated narration for a language you do not speak, for a long book you are short of time on, or when you want a different character voice.
Where the volume controls live
- Per page — the narration level, the page video’s sound, and the photo timing.
- Per project — the story music level and the ducking switch.
Three volume sliders and one ducking switch is the whole mixer. There is deliberately no waveform, no timeline, and no trimming or fades — those are on the roadmap, and they are genuinely unpleasant to use on a phone.
Platform note
Audio mixing in exported video works on Android and iOS. Narration, page video sound, and story music are all mixed in on either platform.
One small difference: imported audio can be MP3, M4A, WAV, or AAC on both, and Android additionally accepts OGG. If you have an OGG file and an iPhone, convert it first.
