↑If a consonant is doubled after a vowel, it is geminated; all consonants can be geminated except for /z/ and /ʒ/. In بین الاقوامی صوتیاتی ابجد, gemination can be represented either by doubling the consonant (fatto/ˈfattə/, miezzo/ˈmjettsə/) or by the length marker ‹ ː ›. Neapolitan, like standard اطالوی زبان, also has a sandhi phenomenon called syntactic gemination, usually represented graphically: e.g. è ssoje/ɛ sˈsɔːjə/.
^ ابپتٹ/b/, /dʒ/, /ʝ/, /ɲ/ and /ʃ/ are always geminated after a vowel.
^ ابپتٹAfter a nasal, /p/, /t/, /tʃ/, /k/ and /ts/ are replaced by their voiced counterparts [b], [d], [dʒ], [ɡ], [dz].
^ ابWhen not preceded by ⟨n⟩, ⟨z⟩ can represent either /dz/ or /ts/, according to the cases.
↑If the two characters ⟨ɡ⟩ and ⟨⟩ do not match and if the first looks like a ⟨γ⟩, then you have an issue with your default font. See Help:IPA § Rendering issues.
^ ابپThe nasals always assimilate their place of articulation to that of the following consonant. Thus, the n in /nɡ/ is a velar [ŋ], and the one in /nf/~/nv/ is a labiodental [ɱ] (though for simplicity ⟨m⟩ takes its place in this list). A nasal before /b/ is always the labial [m].
↑When not geminated nor following another consonant, /tʃ/ tends to be pronounced [ʃ].
↑Two diphthongs, uo/wo(ː)/ and ie/je(ː)/, are always stressed, unless they are at the very end of a word.
^ ابOpen-mid vowels /ɛ ɔ/ can only appear when the syllable is stressed.
↑After the stressed syllable, /a e o/ change to [ə]. This sound is sometimes also found before the stressed syllable and spelled ⟨e⟩, as is fernì/fərˈni/.
↑Vowels are long when stressed in a non-final open syllable: casa/ˈkɑːsə/ ~ cassa/ˈkassə/, or when compounds of preposition a and an article: a +’o = ô.
