The first objective of this paper is to clarify the real nature of such weakened vowels, focusing on the Su’nid dialect, which is the author’s native language.◆In addition, the author is also conducting research on phonetic accent patterns of the Mongolian language’s Sn’nid dialect, but many counter-examples against the traditional “first syllable stress theory” have been found. Nonetheless, why do Mongolian language studies strongly support the first syllable stress theory. So the second objective is to explain the relationship between weakened vowels and the first syllable stress theory.◆To achieve these two objectives, we conducted some experiments using as test subjects, three speakers whose native language is the Su’nid dialect. We applied the acoustic phonetic method to these experiments. In conclusion, weakness is noticeable in open syllables. If the short vowel of a non-head syllable is a closed syllable, and further pitch is added, the vowel becomes a “medium strong vowel” and weakening does not occur.◆Regarding the relationship between weakened vowels and the first syllable stress theory, I think that it was because there was a merit that a clear explanation could theoretically be established by giving the principle that the first syllable holds all authority.}, pages = {51--75}, title = {モンゴル語スヌト方言に見られる弱化母音:音響音声学的研究}, volume = {3}, year = {} }
