Pictures and sounds
Add your company's pictures and MP3 sounds in Works Studio. Kapi keeps them for the company, places them where you say, and writes a sound's captions from what it hears.
A course names its pictures and sounds in kapi-works.json. Kapi keeps their files for your company, apart from the course, so a bundle carries no picture or sound bytes.
Add them in Works Studio
On a course's page in Works Studio, the + in the chat adds pictures and sounds:
- Pictures: PNG, JPEG or WebP, up to 6 MB each.
- Sounds: MP3, up to 6 MB each, such as a welcome from your manager or a recorded call.
- Up to 10 with one change. Say where each one goes, and Kapi places it.
In a video, each lesson starts with its film, so Kapi places a sound after the film.
Each file goes straight to Kapi's storage. Kapi names it by its SHA-256, not by its file name, and keeps it while a course uses it.
A sound in the course
kapi-works.json lists the sound by its SHA-256:
{
"id": "welcome-sound",
"kind": "audio",
"file": "media/welcome-sound.mp3",
"sha256": "sha256:…",
"speech": true,
"captions": { "en-GB": "media/welcome-sound.en-GB.vtt" }
}A page plays it with an audio block:
{ "type": "audio", "media": "welcome-sound" }Captions
A sound with speech needs captions: a WebVTT file under media/ for each language. The course carries its captions as text. Kapi checks this: captions_missing.
When you add a sound in the chat, Kapi listens to it with Gemini and writes its captions, one sentence at a time with its times. Music and sound effects need none.
What learners get
- The sound plays with the player's own controls, which keyboards and screen readers know.
- The words being said show under it, and its whole transcript opens below it, for anyone who is deaf or has the sound off.
Cost
Listening to a sound uses your company's AI credits, with the change that adds it.
Narration
Kapi's AI voice reads every film caption aloud. Choose the voice in kapi-works.json or on the course's page in Studio; Kapi records each caption once, checks it by listening back, and the film plays to it.
