Answers

General usage

Using Ubuntu, I cannot read CHM and EPub documents, even if I have okular-extra-backends and libchm1 installed. Why?

Ubuntu (thus Kubuntu as well) packages of Okular are compiled without the support for these two formats.

The reason is explained in the following Launchpad report: https://bugs.launchpad.net/kdegraphics/+bug/277007 .

Why the speak options in the Tools menu are grayed out?

Because you don't have a speech service on your system, install the Qt Speech library and they should be enabled
