Read and write the same Serbian sound in both official scripts, then identify it by ear.
Serbian Cyrillic and Latin are one-for-one scripts: each sound has one spelling in each script. Treat lj, nj, dž as single letter groups; they map to љ, њ, џ.
The listening mode uses your browser’s speech synthesis with Serbian (sr-RS) requested. Audio quality depends on an installed Serbian voice; the displayed answer always gives the exact spelling.
