Optional dependencies

Auto-hyphenation is done using CSS hyphenation. To enable CSS hyphenation in WebKitGTK, you will need to install the hyphenation rules, e.g., hyphen-en for English, hyphen-fr for French, etc.

For offline dictionary support, install dictd.

For text-to-speech support, install espeak-ng, or festival, and packages for the individual voices.

For Mobipocket (.mobi) and Kindle File Format (.azw, .azw3) support, you would need Python (2.7 or >= 3.4).
