半開後圓唇元音

半開後圓唇元音是母音的一種，用於部份口語中。代表此音的國際音標符號為⟨ɔ⟩；而其X-SAMPA音標則寫作⟨O⟩。此音的IPA符號是個倒轉的c。另外，除了發音時嘴巴比較張開外，此符號所代表的音與半閉後圓唇元音相似，因此此符號和其所代表的發音在英語中被稱為「開O」(open-o)。此名稱亦可代表此符號，因為此符號的形狀，就像是藉由移除「o」這個字母部份的圈圈來使其「張開」一般。 其元音高度是半開，表示舌頭的位置是在開元音和中元音之間。 其元音舌位是後，表示舌頭的位置會盡可能地朝向口腔後部，但不至于阻礙氣流而被歸類為子音。 其元音圓唇度為突出，即將嘴角聚拢，且嘴唇內側向外露出。 Dum-Tragut (2009:13頁) Traunmüller (1982) harv error: no target: CITEREFTraunmüller1982 (help), cited in Ladefoged & Maddieson (1996:290頁) harv error: no target: CITEREFLadefogedMaddieson1996 (help) Khan (2010:222頁) harv error: no target: CITEREFKhan2010 (help) Ternes & Vladimirova-Buhtz (1999:56頁) harv error: no target: CITEREFTernesVladimirova-Buhtz1999 (help) Carbonell & Llisterri (1992:54頁) McGill (2014)，第308–309頁. sfnp error: no target: CITEREFMcGill2014 (help) McGill (2014)，第308頁. sfnp error: no target: CITEREFMcGill2014 (help) Grønnum (1998:100頁) harv error: no target: CITEREFGrønnum1998 (help) Basbøll (2005:47頁) harv error: no target: CITEREFBasbøll2005 (help) Verhoeven (2005:245頁) harv error: no target: CITEREFVerhoeven2005 (help) Collins & Mees (2003:132頁) harv error: no target: CITEREFCollinsMees2003 (help) Collins & Mees (2003:132, 222 and 224頁) harv error: no target: CITEREFCollinsMees2003 (help) Collins & Mees (2003:222頁) harv error: no target: CITEREFCollinsMees2003 (help) Gussenhoven (1992:47頁) harv error: no target: CITEREFGussenhoven1992 (help) 引用错误：没有为名为hce97的参考文献提供内容 Wells (1982:305頁) Mannell, Cox & Harrington (2009) harv error: no target: CITEREFMannellCoxHarrington2009 (help) Bauer et al.
