This article deals with the phonology and phonetics of Standard Modern Greek. For phonological characteristics of other varieties, see varieties of Modern Greek, and for Cypriot, specifically, see . Greek linguists do not agree on which consonants to count as phonemes in their own right, and which to count as conditional allophones. The table below is adapted from , who considers the palatals and both affricates, t͡s and d͡z, to be allophonic. The alveolar nasal /n/ is assimilated to following obstruents; it can be labiodental (e.g. αμφιβολία [aɱfivoˈlia] 'doubt'), dental (e.g. άνθος [ˈan̪θos] 'flower'), retracted alveolar (e.g. πένσα [ˈpen̠sa] 'pliers'), alveolo-palatal (e.g. συγχύζω [siɲˈçizo] 'to annoy'), or velar (e.g. άγχος [ˈaŋхos] 'stress'). Voiceless stops are unaspirated and with a very short voice onset time. They may be lightly voiced in rapid speech, especially when intervocalic. /t/'s exact place of articulation ranges from alveolar to denti-alveolar, to dental. It may be fricated [θ̠ ~ θ] in rapid speech, and very rarely, in function words, it is deleted. /p/ and /k/ are reduced to lesser degrees in rapid speech. Voiced stops are prenasalised (which is reflected in the orthography) to varying extents, and sometimes not at all. The nasal component—when present—does not increase the duration of the stop's closure; as such, prenasalised voiced stops would be most accurately transcribed [mb nd ŋɡ] or [m͡b, n͡d, ŋ͡ɡ], depending on the length of the nasal component. Word-initially and after /r/ or /l/, they are very rarely, if ever, prenasalised. In rapid and casual speech, prenasalisation is generally rarer, and voiced stops may be lenited to fricatives. That also accounts for Greeks having trouble disambiguating voiced stops, nasalised voiced stops, and nasalised voiceless stops in borrowings and names from foreign languages such as, d, nd, and nt, which are all written ντ in Greek. /s/ and /z/ are somewhat retracted ([s̠, z̠]); they are produced in between English alveolars /s, z/ and postalveolars /ʃ, ʒ/.
