The phonology of the Hungarian language is notable for its process of vowel harmony, the frequent occurrence of geminate consonants and the presence of otherwise uncommon palatal stops.
This is the Hungarian consonantal system, using symbols from the International Phonetic Alphabet (IPA).
Almost every consonant may be geminated, written by doubling a single letter grapheme: ⟨bb⟩ for [bː], ⟨pp⟩ for [pː], ⟨ss⟩ for [ʃː] etc., or by doubling the first letter of a grapheme cluster: ⟨ssz⟩ for [sː], ⟨nny⟩ for [ɲː], etc.
The phonemes /d͡z/ and /d͡ʒ/ can appear on the surface as geminates: bridzs [brid͡ʒː] ('bridge (the card game)'). (For the list of examples and exceptions, see Hungarian dz and dzs.)
Hungarian orthography does not use háčky or any other consonant diacritics like the surrounding Slavic languages. Instead, the letters c, s, z are used alone (/t͡s/, /ʃ/, /z/) or combined in the digraphs cs, sz, zs (/t͡ʃ/, /s/, /ʒ/), while y is used only in the digraphs ty, gy, ly, ny as a palatalization marker to write the sounds /c͡ç/, /ɟ͡ʝ/, /j/ (formerly /ʎ/), /ɲ/.
