Kokorokodi does not work offline?

With more than 13 GB downloaded, I’m still unable to make it work offline.

For example, it downloads the voice successfully, but as soon as I disconnect from the Internet, it fails to generate the .wav file, even though it reports that the process has completed.

How can I make it work completely offline?

Every time I generate audio, it downloads the same voice again, which takes one or two minutes and uses a significant amount of bandwidth before processing starts.

My Internet usage is metered when I’m away from home, so repeatedly downloading the same voice is a problem.

I specifically downloaded several voices so I could work offline, but the application still reconnects to the Internet and downloads those same voices again instead of using the copies already stored locally.

Am I missing a configuration step, or is offline mode not currently supported?

It is a docker container that has ephemeral storage and no obvious way to cache to host storage. Docker containers do not generally have write access to everywhere on the host. The docker container approach greatly simplifies installation for the user. Someone would have to add a command line parameter to it to tell it where to get a manually downloaded voice and then somehow integrate that with Shotcut. Alas, that is very low priority for me, and I leave it as a task for someone else.
