All voicedobstruents/b, d, ɡ, v, z, ʐ, ʑ, dʐ, dʑ/ are devoiced (so /d/ becomes t, etc.) at the ends of words and in clusters ending in any unvoiced obstruents /p, t, k, f, s, x, ʂ, ɕ, tʂ, tɕ/. The voiceless obstruents are voiced (/x/ becoming [ɣ], etc.) in clusters ending in any voiced obstruent except /v, ʐ/, which are themselves devoiced in this case.
↑ 1.01.11.21.220.127.116.11.71.81.9The letter ‹i›, when followed by a vowel, either represents a pronunciation like a ‹j› or a "soft" pronunciation of the preceding consonant (so pies is pronounced as if it were spelt ‹pjes›).
It has the same effect as an acute accent on alvoelar consonants (‹s›, ‹z›, ‹c›, ‹dz›, ‹n›). So się, cios and niania are pronounced as if they were spelt ‹śę›, ‹ćos›, ‹ńańa›. A following ‹i› also softens consonants when it is itself pronounced as a vowel, so for example zima, ci and dzisiaj are pronounced as if spelled ‹źima›, ‹ći›, ‹dźiśaj›.
↑ 2.02.12.22.32.42.5Affricates such as /ts/ and /dʐ/) are correctly written with tie-bars: /t͡s/, /d͡ʐ/. The tie-bars are omitted in the above chart, as they do not display correctly in all browsers. Nonetheless, Polish does contrast affricates with stop + fricative clusters, like czysta[ˈt͡ʂɨsta] "clean" versus trzysta[ˈtʂɨsta] "three hundred".
↑ 3.03.13.23.33.43.5Polish makes contrasts between retroflex and alveolo-palatal consonants, both of which sound like the English postalveolars /ʃ ʒ tʃ dʒ/ The retroflex sounds are pronounced "hard" with the front of the tongue raised, and the alveolo-palatal sounds are "soft" with the middle of the tongue raised, adding a bit of a ‹y› or ‹ee› sound to them.
↑ 4.04.14.24.34.44.5The letters ‹ą› and ‹ę› represent the nasal vowels/ɔ̃, ɛ̃/, except when followed by a stop or affricate, where they represent oral vowels /ɔ, ɛ/ followed by a nasal consonant homorganic with the following stop or affricate (e.g. kąt[ˈkɔnt], gęba[ˈɡɛmba], ręka[ˈrɛŋka], piszący[pʲiˈʂɔnt͡sɨ], pieniądze[pʲeˈɲɔnd͡zɛ], pięć[ˈpʲeɲt͡ɕ], jęczy[ˈjɛnt͡ʂɨ]).
