半閉前不圓唇元音

半閉前不圓唇元音是母音的一種，國際音標以⟨e⟩代表此音，而X-SAMPA音標也以⟨e⟩代表此音。 其元音高度是半閉，表示舌頭的位置是在閉元音和中元音之間。 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。 Traunmüller (1982), cited in Ladefoged & Maddieson (1996:290頁) Ternes (1992)，第433頁.
