Consonants
As a general idea, consonnants don't distinguish voiced and unvoiced, explaining the [~] between two letters of the IPA. 1 When followed by /f~v/ 2 When followed by /k~g/ 3 When /i/ is followed by /j/; or when a descending diphthong is followed by an ascending diphthong of the same nature (e.g. /äj.jä/ -> /äj.çä/) 4 Associated with the digrams "dz" and "dj" 5 When /u/ is followed by /w/; or when a descending diphthong is followed by an ascending diphthong of the same nature (e.g. /äw.wä/ -> /äw.ʍä/ 6 This sound isn't written, but implied within the text and speech. It's used instead of the glottal stop, between vowels or in a beginning of a word that begins with a vowel.

Vowels
1 In diphthongs "wo" and "ow"; and when followed by two consonants in the same word.
