A Study On Factors Affecting The Stress Of Mongolian Words

Based on the "Mongolian Word Stress Study Database",the paper has conducted in-depth research on the factors that affect word stress.The paper is composed of three parts: introduction,text and conclusion.The introduction mainly explains the reasons for selecting the topic,the purpose and impact of the research,the research materials and research methods,and the general situation of Mongolian word stress research.The first chapter starts with the acoustic parameters,statistically analyzes the vowel acoustic parameters of Mongolian disyllabic words,including duration,pitch and intensity,and summarizes the duration,pitch,and intensity of disyllabic words with different structures in Mongolian.From the research results,it can be seen that in the vowel length models of disyllabic words with different structures,not only the "long and short structure" and "short and long structure" exist,but in some cases,the "equal structure" may also appear.In the two-syllable pitch model,there are "high and low structure","low and high structure",and a small amount of "equal structure".In addition,the pitch model has different central models when used alone and in different phonetic patterns with different sentence patterns.In the two-syllable sound intensity model,"strong and weak structure" and "weak and strong structure" appear.For a certain syllable,there are many cases of long syllabic disyllabic words in which the syllabic intensity is stronger in the long syllabic syllables,but in the two-syllabic words composed of all short syllabic words,which syllable is streesed is relative freedom.The second chapter,according to whether the word structure contains ultra-short vowels,the vowel consonants of the word structure,etc.,has studied the factors that affect the stress of words more deeply.Through the study of the changes of acoustic parameters of vowels with and without ultra-short sounds in two-syllable words,it is found that whether the pronunciation of the same word with ultra-short vowels has no effect on the stress of words.According to the change of the vowel consonant composition in the syllable of the two-syllable word,the duration,pitch,and intensity models will also change accordingly.Therefore,it is concluded that the change of syllable structure vowel consonant composition has a certain influence on the word stress model.
