Xiôngū Tuái Phè

Introduction
Xiọ̌ngū Tuái Phè [ˈʑjo˩˥ŋu twal˦ ɸe˨] (Xiongu) is a language I'm creating. It is an isolation tonal language that's inspired by Chinese and Vietnamese. It has 18 consonants and 5 vowels with 4 sets of tones, making 20 vowels in total. The four tones are high, mid, low, and falling. Morphology is non-existent in the language, so particles replace affixes. For example, the word rōm means "many", so it is used as a plural marking.
