Diphthong au to Voiceless labiodental fricative
The diphthong /au/ can undergo a fascinating transformation where its vowel-like offglide becomes a consonant. This process, known as consonantalization, turns the /u/ element of the diphthong into a labiodental fricative, which can be either voiced ([v]) or voiceless ([f]), depending on the sounds around it.
