Onetop: - /iə/ and /uə/ are removed as i feel that these two are redundant, since they can be easily recreated with /iː/, /uː/ and /ə/; - /æ̃/ and /ɒ̃/ are merged into /◌̃/, which can only be used on /æ/ and /ɒ/ in french loanwords; - /l̩/, /m̩/ and /n̩/ are merged into /◌̩/, which can only be used on /l/, /m/ and /n/ in words with syllabic consonants; - /ˈ◌/ and /ˌ◌/, representing primary and secondary stress respectively, are added. Unafon: - /β/, /ð/, /ɣ/, /ɱ/ and /ŋ/ are no longer optional; - The /tɬ/ and /ts/ sounds from other dialects of Spanish are added; - /ˈ◌/, which represents primary stress, is added.
Credit to all.
