A Study on the Weak Vowels of Shuluun HuhVatois in Modern Mongolian

Stressed,unstressed and weak syllable is a relative concept in phonological words with the measurable phonetic parameter.Stressed vowel is high,heavy,and short,while weak vowel is low weak and long,the between is the unstressed vowel.In multi-syllable words,primary stress usually falls on the second syllable,while the relative weak vowel is placed on derivative syllable.In the word without derivative syllable,stressed and unstressed vowel is the only pare of control point.Weak vowel caused by syllable composition belongs to structural weak vowel.Open and blocked syllable followed by heavy syllable with consonant onset is the structural reasons for vowel weakness,while aspirated consonants make up the phonetic reasons,and the quickened speech is the motive reason.
