It's another one of these "this could be spoken somewhere in the former Soviet Union and therefore uses Cyrillic, by the way it uses letters that are not used together in the alphabet of any actual language and the phonemic-orthographic correspondences match suspiciously well in spite of the weirdness of both the phonology and orthography but who cares??? it's just a conlang bro XD"-type of phonologies that everyone makes at least one of, usually in the early stages of their conlanging journey...
I unironically like this kind of phonologies and orthographies tbh.
/m n ŋ/ <м н ӈ>
/p b t d k q/ <п б т д к ӄ>
/t͡s t͡ʃ t͡ʂ/ <ц ч ҷ>
/s ʃ ʂ/ <с ш щ>
/β j x ɣ χ ʁ/ <в й х г ӽ ҕ>
/r l/ <р л>
/ɑ ə ɨ o u/ <а э ы о у>
/ʲɑ ʲe ʲə ʲi ʲɨ ʲo ʲu/ <я е є і и ё ю>
/m̩ n̩ j̩ ɰ̩/ <ӎ ң ь ъ>
/ʲɑ ʲe ʲə ʲi ʲɨ ʲo ʲu/ are [jɑ je jə ji jɨ jo ju] word-initially and after vowels, [i̯ɑ i̯e i̯ə i i̯ɨ i̯o i̯u] after consonants with palatalisation on the consonant.
/ɨ o u/ are [ɯ ɔ ʊ] after /q t͡ʂ ʂ χ ʁ/.
/m̩/ causes preceding vowels to be nasalised, as well as a nasalised glottal stop [ʔ̃] being inserted.
/n̩/ assimilates homogranically to the following consonant and causes preceding vowels to be nasalised, as well as a nasalised glottal stop [ʔ̃] being inserted. Word-finally, it's [ŋ̩].
/j̩/ is usually [ɘ̆] and causes preceding consonants to be palatalised. It's devoiced [ɘ̥̆] between voiceless consonants. Word-finally, it can be realised as simply palatalisation on the preceding consonant if the next word begins with a vowel.
/ɰ̩/ is usually [ʌ̆] and causes preceding consonants to be velarised. It's devoiced [ʌ̥̆] between voiceless consonants. Word-finally, it can be realised as simply velarised on the preceding consonant if the next word begins with a vowel.
/p t k t͡s t͡ʃ t͡ʂ/ are often aspirated word-initially.
/n t d t͡s s l/ are usually dental [n̪ t̪ d̪ t̻͡s̪ s̪ l̪].
/q t͡ʂ ʂ χ ʁ/ occur only before /ɑ ə ɨ o u/.
/m n p t t͡s s β r l/ are [mʲ n̪ʲ pʲ t̪ʲ t̻͡s̪ʲ s̪ʲ βʲ rʲ l̪ʲ] when palatalised.
/ŋ k t͡ʃ ʃ x ɣ/ are [ɲ c t͡ɕ ɕ ç ʝ] when palatalised.
/r/ is [ɾ] intervocalically.
Stress falls on the first open syllable of a word. If all syllables are closed, then it's on the first syllable unless the first syllable contains a syllabic consonant; in that case it falls on the first syllable that contains a full vowel (no idea what happens if all the vowels in a word are syllabic consonants, I guess then nothing is stressed). Stressed syllables are pronounced with long vowels.
Gibberish example:
