The sonority files contain both configuration option on syllabification and the enriched sonority scale (lexicon). The former section is called [General] the latter [Segments].
Watch out! Sonority files are not guaranteed to work across releases. In fact, while you can freely change the [Segment] section (since the 0.9.7 release), there is no warranty that options in [General] will always be the same. If you’re using a sonority file of a different release, as indicated in the header section, Sylli may not work properly!
If this is the case, look for differences in the [General] section, or simply rewrite you sonority by copy-pasting the section from the default one.
The [General] section defines everything that can be customise and does not regard the segment inventory. It contains everything you can find in the UI (ref...). Note that changing any option in the UI will not affect the sonority file. Here is a richly coded example from the default sonority file.
Here you specify your segment inventory. Every input you will give to Sylli will be converted into a phonological object with the characteristics specified in the option values (right of the equation). The segment in the left specifies the input to be converted.
