How to Upload Sound Recordings for the Alphabet Lessons
What this guide covers
The Learn Klo alphabet lesson lets learners tap a letter and hear it spoken by a real Krobo voice. Right now, every letter is waiting for that real recording — we never use computer-generated or invented voices anywhere in this project. This guide explains exactly how a set of real recordings gets from a phone or microphone into the live app.
“We never invent Krobo words, spellings, or pronunciations. If a letter hasn't been confirmed by a real speaker yet, the app honestly says so instead of guessing.”
The alphabet, letter by letter
Two short clips are needed for each of the 30 letters and letter-combinations in the current working sequence:
Before you record — what we need per letter
| Clip | What it should contain |
|---|---|
| Letter name | The speaker says the name of the letter, clearly and naturally. |
| Letter sound | The speaker demonstrates the sound the letter makes. |
Recording tips
- Record somewhere quiet, without background noise, wind, or echo.
- Hold the microphone or phone a comfortable distance from the speaker's mouth.
- Keep each clip short — just the name or sound, with a little silence before and after.
- If a recording doesn't sound clean, record it again — a second take costs nothing.
- A phone's built-in voice recorder app is perfectly fine for this.
From recording to the live app

1
Record the sounds
Work with a native Krobo speaker to record the "letter name" and "letter sound" clips above. It's fine to do this one letter at a time, or a few at once — you don't need all 30 before sending anything.
-
2
Name your files clearly
Give each recording a simple file name that says which letter and which clip type it is — for example, the letter "A" might produce A-name.mp3 and A-sound.mp3. This lets our team match every recording to the right letter without guesswork.

Send the recordings to the project team
Share the audio files with whoever is coordinating the technical side (currently Eric) — a shared folder, a message with attachments, or a hand-off if you're local. There's no upload button in the app for this yet, which also means every recording gets a human look before it goes near the app.

The team adds your recordings to the app
Once received, recordings are connected to the correct letters — carefully, one at a time, so nothing gets mixed up.

5
A native speaker or reviewer confirms accuracy
Before a recording is marked trustworthy in the app, someone with real authority on the Krobo language confirms the name, sound and spelling are correct. A recording existing isn't the same as it being approved — this step protects the accuracy the whole project depends on.

6
It goes live
Once approved, the recording appears in the alphabet lesson for every learner to hear — checked on a real phone before it's called done.
Only have a few recordings, not all 30? That's completely fine, and encouraged. Even one or two solid, clean recordings is real progress — the alphabet lesson can go live letter by letter as recordings come in, without waiting for all 30 at once.
Who to contact
Ready to send recordings, or have questions about equipment or format? Reach out to the project coordinator before you start recording — a quick check-in up front can save a re-recording session later.
