中前不圆唇元音

中前不圆唇元音 是在一些语言发音中出现的一种元音。 虽然IPA没有专门表示介于半闭的/e/和半开的/ɛ/间正中位置元音的符号，此音通常写作 e。而若欲准确表示，则可使附加符，如 e̞ 或 ɛ̝（前者更多见）。一些汉学家和韩学家则使用 ᴇ（小字大写E, U+1D07, ᴇ）。 许多音系中“中元音区”（即非闭亦非开）只有一个不圆唇元音的语言，通常将之发作真正的中元音（与半闭和半开元音均有差异），包括西班牙语、日语、韩语、希腊语和土耳其语等。英语的许多方言亦有此音。然而，这点却并非能通用。例如，尽管都没有其他前不圆唇元音，但伊博语的是/e/，而保加利亚语中则是/ɛ/。 据称，分布于马来西亚和泰国的肯休语可以独一无二地区分仅在半闭、中和半开上有所差异的三个前不圆唇元音。[來源請求] 中前不圆唇元音的特徵包括： 其元音高度為中，舌頭的位置約恰在閉元音與開元音之間。 其元音舌位是前，表示舌頭會盡可能地朝向嘴巴前面，但不至于阻礙氣流而被歸類為子音。通常圓唇前元音的實際位置會比參考點的位置還要更靠近中央（稱此過程為央化（英语：Relative articulation#Centralized））。因此，前元音事實上常常是次前元音。 其圓唇度為不圓唇元音，嘴唇自然放鬆，不特別向前突起。 Jarrah, Mohamed Ali Saleh (1993) harv error: no target: CITEREFJarrah,_Mohamed_Ali_Saleh1993 (help) Traunmüller (1982) harv error: no target: CITEREFTraunmüller1982 (help), cited in Ladefoged & Maddieson (1996:290頁) harv error: no target: CITEREFLadefogedMaddieson1996 (help) Recasens (1996:59-60頁) harv error: no target: CITEREFRecasens1996 (help) Dankovičová (1999:72頁) harv error: no target: CITEREFDankovičová1999 (help) Uldall (1933) harv error: no target: CITEREFUldall1933 (help), cited in Ladefoged & Maddieson (1996:289頁) harv error: no target: CITEREFLadefogedMaddieson1996 (help) Ladefoged & Johnson (2010:227頁) harv error: no target: CITEREFLadefogedJohnson2010 (help) Grønnum (1998:100頁) harv error: no target: CITEREFGrønnum1998 (help) Grønnum (2005:268頁) harv error: no target: CITEREFGrønnum2005 (help) Grønnum (2003) harv error: no target: CITEREFGrønnum2003 (help) Basbøll (2005:45頁) harv error: no target: CITEREFBasbøll2005 (help) John Wells's phonetic blog: Danish. 5 November 2010 [11 March 2015]. （原始内容存档于2020-11-02）.  Allan, Holmes & Lundskær-Nielsen (2000:17頁) harv error: no target: CITEREFAllanHolmesLundskær-Nielsen2000 (help) Peters (2010:241頁) harv error: no target: CITEREFPeters2010 (help) Coupland (1990:95頁) Roach (2004:242頁) harv error: no target: CITEREFRoach2004 (help) Labov, William; Ash, Sharon; Boberg, Charles.
