WhatsApp to Yoto
Turn a WhatsApp voice note into a Yoto card before bedtime.
Published by Spoken Letter · 2 min read
You already have the recording. It is sitting in a WhatsApp chat — Grandad reading a page of a picture book, an auntie singing the song only she knows. Getting it onto a Yoto card sounds like it needs software and patience. It needs neither. Save the file, upload it, and Spoken Letter does the rest.
Three Steps
Step 1: Save the Voice Note Out of WhatsApp
On iPhone, open the chat, press and hold the voice message, tap Forward, then tap the share icon and choose Save to Files. On Android, press and hold the message, tap the three-dot menu, choose Share, and save it to your phone. Either way you end up with an audio file you can find again. If you would rather not hunt through folders, forward the message to yourself by email instead — the attachment is the same file.
Step 2: Upload the File to Spoken Letter
Open Spoken Letter on the same phone, start a story, and choose to upload a file instead of recording a new one. Pick the voice note you just saved. There is no microphone to set up, no cable, and no gear to buy — the message you already have is the recording.
Step 3: Download It, or Send It Straight to Yoto
Gemini shapes the audio into a bedtime-length script and leaves the voice exactly as it was recorded. Then you choose: download the MP3 pack and load the card yourself, or send it straight to your connected Yoto account. There is no separate approval screen — the download or the send is the approval. A brand-new Make Your Own card needs one manual link, once in the Yoto app, because Yoto has no API for that step. After that, every story you send lands on the same card.
Before You Send
How Long Should the Voice Note Be?
Three to seven minutes suits a young listener. A thirty-second hello works too, and often gets played more than a long one. What does not work is twenty minutes of group-chat rambling: the good part is buried, and a child will not wait for it. If the note is long, send the two minutes that matter.
If the File Will Not Behave
WhatsApp saves voice messages as .opus on Android and .m4a on iPhone. Both upload fine, so do not convert anything first. A few seconds of silence at the start is normal — that is the sender pressing record before speaking — and it is not worth fixing. Background noise is the one thing worth asking for a second take over. A television, a kitchen fan, or a speakerphone echo stays in the file, because nothing is stripped out of the recording itself. One more take in a quiet room settles it.
A Worked Example: The Birthday Message That Kept Playing
A grandmother in Seville sends a two-minute birthday message on WhatsApp — a bit of singing, then the story of the year her granddaughter was born. The parents save the file, upload it, and have a finished MP3 before the tea goes cold. They download the pack, load it onto a Make Your Own card, and it plays at bedtime that night. Six months later it is still the card their daughter asks for.
