А есть другие диалекты (и сюда относится европейский португальский), где классическая шва в позиции перед носовой, а в остальных позициях звук несколько ниже.

Это был такой большой сра спор фонетистов, существует ли в бразильском фонема /ɨ/

The exact realization of the /ɐ/ varies somewhat amongst dialects. In Brazil, the vowel can be as high as [ə] in any environment. It is typically closer in stressed syllables before intervocalic nasals /m, n, ɲ/ than word-finally, reaching as open a position as [ɐ] in the latter case, and open-mid [ɜ] before nasals,[35] where /ɐ/ can be nasalized. In European Portuguese, the general situation is similar, except that in some regions the two vowels form minimal pairs in some European dialects.[36] In central European Portuguese this contrast occurs in a limited morphological context, namely in verbs conjugation between the first person plural present and past perfect indicative forms of verbs such as pensamos ('we think') and pensámos ('we thought'; spelled ⟨pensamos⟩ in Brazil). Spahr[37] proposes that it is a kind of crasis rather than phonemic distinction of /a/ and /ɐ/. It means that in falamos 'we speak' there is the expected prenasal /a/-raising: [fɐˈlɐmuʃ], while in falámos 'we spoke' there are phonologically two /a/ in crasis: /faˈlaamos/ > [fɐˈlamuʃ] (but in Brazil both merge, falamos [faˈlɐ̃mus]).

кто ж спорит? просто когда говорят «я предпочитаю современный греческий античному» чтение упаковок как-то не приходит на ум
