A mid vowel (or a true-mid vowel) is any in a class of vowel sounds used in some spoken languages. The defining characteristic of a mid vowel is that the tongue is positioned mid-way between an open vowel and a close vowel. ==Vowels== The only mid vowel with a dedicated symbol in the International Phonetic Alphabet is the mid central vowel with ambiguous rounding . The IPA divides the vowel space into thirds, with the close-mid vowels such as or and the open-mid vowels such as or equidistant in formant space between open or and close or . Thus a true mid front vowel can be transcribed as either a lowered (with a lowering diacritic) or as a raised (with a raising diacritic). Typical truly mid vowels are thus: * mid front unrounded vowel or (commonly written as if it were close-mid) * mid front rounded vowel or (commonly written as if it were close-mid) * mid central unrounded vowel or (most commonly written ) * mid central protruded vowel or (most commonly written as if it were close-mid) * mid central compressed vowel * mid back unrounded vowel or (commonly written as if it were close-mid) * mid back rounded vowel or (commonly written as if it were close-mid) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「mid vowel」の詳細全文を読む スポンサード リンク
