Something meant to be reminiscent of Spanish, German/Yiddish, Hungarian, French, Portuguese, Basque, Polish, Irish, etc. but not too much like any of them. Not sure if I succeeded, but I'm still pretty happy with this phonology and might use it (or something similar) for some kind of conlang sooner or later, if I got around to making one set anywhere in Europe...
Phonemes with two realisations separated by ~ indicate realisations before front and back vowels respectively, and phonemes with two realisations separated by - indicate realisations in onset and coda respectively. I'm just too lazy to write down those allophonic rules and wouldn't be sure which of the allophones to refer to as the phoneme, so yeah, I indicated them in the phonemic inventory itself.
/m n ɲ-ŋ/ <m n gn>
/p b t d k g/ <p b t d k g>
/t͡ʃ~c d͡ʒ~ɟ/ <tj dj>
/t͡s/ <tz>
/s ʃ/ <z x>
/f v θ j x ɦ-h/ <f v s j ch h>
/ɹ~ʀ-ʒ~æ̯/ <r>
/rː~ʀː/ <rr>
/l~ɫ-l~w ʎ/ <l gl>
/a e i o u ə ø y/ <a e i o u y ö ü>
/aː eː iː oː uː əː øː yː/ <á é í ó ú ý ő ű>
/m n ɲ-ŋ/ induce nasalisation in closed syllables, and /n/ is also dropped afterwards word-finally and before fricatives
/d g/ are [ð ɣ] intervocalically, including across word boundaries as a sandhi effect; this also occurs after allophonic nasalised vowels
word-final /ɦ/ is [h] in coda, except [ʔ̚] word-finally as a sandhi effect before words beginning with a vowel
/rː~ʀː/ occurs only intervocalically inside words, but it's considered a single consonant since vowels before it have open syllable allophones
/a e i o u ə ø y/ and tend to be [a ɛ i o u ə ø y] in open syllables
/aː eː iː oː uː əː øː yː/ and tend to be [aː ɛː iː oː uː əː øː yː] in open syllables
/a e i o u ə ø y/ and tend to be [æ ɐ ɪ ɔ ʊ ə ɞ ʏ] in closed syllables; [ɐ] is still treated as a front vowel
/aː eː iː oː uː əː øː yː/ and tend to be [æː ɑː ɪː ɔː ʊː əː ɞː ʏː] in closed syllables; [ɑː] is still treated as a front vowel
Word-initial vowels are preceded by a non-phonemic glottal approximant [ʔ̞], except following word-final /ɦ/, in which case it is a glottal stop [ʔ].
