Vowels
Monophthongs
Front | Central | Back | ||||
---|---|---|---|---|---|---|
unrounded | unrounded | rounded | ||||
short | long | short | long | short | long | |
Close | i | iː | u | uː | ||
Mid | e | eː | o | (oː) | ||
Open | (æ) | a | aː |
Symbols
- The close vowels are variably transcribed with the symbols ⟨i, iː, u, uː⟩ (without diacritics)[3] and ⟨i̞, i̞ː, u̞, u̞ː⟩ (with a lowering diacritic).[4] This article uses the former set for simplicity.
- The mid vowels are variably transcribed with the symbols ⟨e, eː, o, oː⟩,[5] ⟨ɛ, ɛː, ɔ, ɔː⟩[6] and, most rarely, with ⟨e̞, e̞ː, ɔ̝, ɔ̝ː⟩.[7] This article uses the first set for simplicity.
- The open central vowels are most often transcribed with the symbols ⟨a, aː⟩,[8] but Mistrík (1988) transcribes them with ⟨ɑ, ɑː⟩, whereas Pavlík (2004) transcribes them as ⟨ɐ̞, ɐ̞ː⟩. This article uses the first set for simplicity.
Phonetic realization
- The close vowels /i, iː, u, uː/ vary in their height between close [i, iː, u, uː] and near-close [ɪ, ɪː, ʊ, ʊː], with the near-close realization being the most usual. The backness of /i, iː/ varies between fully front [i ~ ɪ̟, iː ~ ɪ̟ː] and near-front [i̠ ~ ɪ, i̠ː ~ ɪː], just as the backness of /u, uː/ varies between fully back [u ~ ʊ̠, uː ~ ʊ̠ː] and near-back [u̟ ~ ʊ, u̟ː ~ ʊː].[9][10]
- There is not a full agreement about the quality of the mid vowels /e, eː, o, oː/:
- According to Kráľ (1988), Mistrík (1988) and Hanulíková & Hamann (2010), the mid vowels are true-mid [e̞, e̞ː, o̞, o̞ː].[11][12][13] However, the first of these authors lists other possible pronunciations:
- Long /eː, oː/ are realized as close-mid [eː, oː] in southern dialects spoken near the river Ipeľ, as well as - under Hungarian influence - in some other speakers. He does not report the occurrence of the close-mid realizations [e, o] of the short /e, o/.[12]
- Open-mid realizations [ɛ, ɛː, ɔ, ɔː] are rare.[12]
- According to Pavlík (2004):
- /e, eː/ vary in their height between close-mid [e, eː] and true-mid [e̞, e̞ː], with the true-mid realization being the most usual. The backness of these vowels varies between fully front [e ~ e̞, eː ~ e̞ː] and near-front [e̠ ~ e̠˕, e̠ː ~ e̠˕ː]. The open-mid realizations [ɛ, ɛː] do not occur in standard Slovak.[14]
- /o, oː/ vary between true-mid [o̞, o̞ː] and open-mid [ɔ, ɔː], with the true-mid realization being the most usual. The backness of these vowels varies between fully back [o̞ ~ ɔ, o̞ ~ ɔ] and near-back [o̟˕ ~ ɔ̟, o̟˕ː ~ ɔ̟ː]. The close-mid realizations [o, oː] do not occur in standard Slovak.[14]
- According to Kráľ (1988), Mistrík (1988) and Hanulíková & Hamann (2010), the mid vowels are true-mid [e̞, e̞ː, o̞, o̞ː].[11][12][13] However, the first of these authors lists other possible pronunciations:
- Speakers often fail at attempts to pronounce /æ/, pronouncing a vowel that is phonetically too close to either /e/ or /a/.[15]
- There is not a complete agreement about the quality of the vowels transcribed /a, aː/:
- According to Kráľ (1988), they are either open central [ä, äː] or somewhat more back [ɑ̟, ɑ̟ː], with both variants being equally correct in standard Slovak. He also states that under Hungarian influence, some speakers pronounce the short /a/ as rounded [ɒ].[16]
- According to Mistrík (1988), they are open advanced back [ɑ̟, ɑ̟ː].[11]
- According to Hanulíková & Hamann (2010), these are open central [ä, äː].[17]
- According to Pavlík (2004), these vary in quality between near-open central [ɐ, ɐː], open retracted front [a̠, a̠ː], open central [ä, äː] and open advanced back [ɑ̟, ɑ̟ː], with the open central realizations being the most usual.[18]
Other notes
- Vowel length is not phonemic in Eastern dialects, whereas in Western dialects, vowels that are short due to the rhytmical law are often realized as long, and thus violating that law.[19]
- /y, yː, ø, øː, oː/ occur only in loanwords.[1][20][21] Just as other mid vowels, /ø, øː/ are phonetically true-mid [ø̞, ø̞ː].[22] Among these vowels, only /oː/ is consistently realized in the correct manner, whereas the occurrence of the front rounded vowels /y, yː, ø, øː/ has been reported only by Kráľ (1988), who states that the front rounded vowels appear only in the high register and medium register. However, in the medium register, /y, yː/ and /ø, øː/ are often either too back, which results in realizations that are phonetically too close to, respectively, /u, uː/ and /o, oː/, or too weakly rounded, yielding vowels that are phonetically too close to, respectively, /i, iː/ and /e, eː/.[23]
- /uː, eː/ do not occur after soft consonants, where they are replaced by the corresponding diphthongs /i̯u, i̯e/. The same is generally true for /aː/ (/i̯a/ after soft consonants), but the sequence /jaː/ may occur in some cases.[24]
- Long /eː/ occurs only in loanwords, one native word (dcéra) and in adjective endings.[25]
- /æ/ can only be short, and occurs only after /m, p, b, v/.[1][15] There is not a full agreement about its status in the standard language:
- Kráľ (1988) states that the correct pronunciation of /æ/ is an important part of the high register, but in medium and low registers, /æ/ merges with /e/, or (in some cases) with /a/.[15]
- Short (2002) states that only about 5% of speakers have /æ/ as a distinct phoneme, and that even when it is used in formal contexts, it is most often a dialect feature.[26]
- Hanulíková & Hamann (2010) state that the use of /æ/ is becoming rare, and that it often merges with /e/.[1]
Diphthongs
Ending point | |||
---|---|---|---|
Front | Central | Back | |
Unrounded | i̯e | i̯a | i̯u |
Rounded | u̯o |
- These diphthongs are variably transcribed as ⟨i̯e, i̯a, i̯u, u̯o⟩,[5] ⟨i̯ɛ, i̯a, i̯u, u̯ɔ⟩,[28] ⟨ɪ̯ɛ, ɪ̯a, ɪ̯ʊ, ʊ̯ɔ⟩[29] and ⟨ɪ̞̆e̞, ɪ̟̆ă, ɪ̞̆ʊ, ŭ̞o̞⟩.[7] For simplicity, this article uses the first set of symbols.
- All of the diphthongs are rising, i.e. their second elements have more prominence.[27][30]
Consonants

---|---|---|---|---|---|---|---|
Nasal | m | n | ɲ | ||||

Trill | rː |
- Voiceless stops and affricates are unaspirated.
- Voiced stops and affricates are fully voiced.
- /n/ is apical alveolar [n̺].[32]
- /t, d, t͡s, d͡z, s, z, ɲ, c, ɟ/ are laminal [t̻, d̻, t̻͡s̻, d̻͡z̻, s̻, z̻, ɲ̻, c̻, ɟ̻].[33]
- /ʎ/ is palatalized laminal denti-alveolar [l̪ʲ],[43] palatalized laminal alveolar [l̻ʲ][31][43][44] or palatal [ʎ].[31][43][44] The palatal realization is the least common one.[31][44]
- Pavlík (2004) describes an additional realization, namely a weakly palatalized apical alveolar approximant [l̺ʲ]. According to this scholar, the palatal realization [ʎ] is actually alveolo-palatal [ʎ̟].[45]
- /l, r/ are apical alveolar [l̺, r̺].[46]
- Postalveolar /t͡ʃ, d͡ʒ, ʃ, ʒ/ are often pronounced hard, i.e. as laminal retroflex (flat postalveolar) [t͡ʂ, d͡ʐ, ʂ, ʐ],[31] as in Russian and Polish.
- /d͡ʒ/ occurs mainly in loanwords.[31]
- /v/ is realized as:
- /j/ is an approximant, either palatal or alveolo-palatal.[48] Between close front vowels, it can be realized as a fricative [ʝ], whereas between open central vowels, it can be a quite lax approximant [j˕].[49]
Some additional notes includes the following (transcriptions in IPA unless otherwise stated):
- /r, l/ can be syllabic: /r̩, l̩/. When they are long (indicated in the spelling with the acute accent: ŕ and ĺ), they are always syllabic, e.g. vlk (wolf), prst (finger), štvrť (quarter), krk (neck), bisyllabic vĺča—vĺ-ča (wolfling), vŕba—vŕ-ba (willow-tree), etc.
- /m/ has the allophone [ɱ] in front of the labiodental fricatives /f/ and /v/.
- /n/ in front of (post)alveolar fricatives has a postalveolar allophone [n̠].
- /n/ can be [ŋ] in front of the velar plosives /k/ and /a/.
Stress
In the standard language, the stress is always on the first syllable of a word (or on the preceding preposition, see below). This is not the case in certain dialects. Eastern dialects have penultimate stresses, which at times makes them difficult to understand for speakers of standard Slovak. Some of the north-central dialects have a weak stress on the first syllable, which becomes stronger and moves to the penultimate in certain cases. Monosyllabic conjunctions, monosyllabic short personal pronouns and auxiliary verb forms of the verb byť (to be) are usually unstressed.
Prepositions form a single prosodic unit with the following word, unless the word is long (four syllables or more) or the preposition stands at the beginning of a sentence.
Official transcriptions
Slovak linguists do not usually use IPA for phonetic transcription of their own language or others, but have their own system based on the Slovak alphabet. Many English language textbooks make use of this alternative transcription system. In the following table, pronunciation of each grapheme is given in this system as well as in the IPA.

Orthographic version
Raz sa severák a slnko hádali, kto z nich je silnejší. V tom zbadali pocestného, ktorý kráčal zakrytý plášťom. Dohodli sa, že silnejší je ten, kto ako prvý dokáže, aby si pocestný vyzliekol plášť. A tak začal severák fúkať zo všetkých síl, ale čím viac fúkal, tým viac sa pocestný zakrýval plášťom. Nakoniec sa severák vzdal zbytočnej námahy. Potom slnko začalo svietiť a hriať. Za malú chvíľku bolo pocestnému teplo a vyzliekol si plášť. Severák musel nakoniec uznať, že slnko je silnejšie ako on.[52]
