/a?/在發(fā)音時(shí)，唇形和舌位從/??/向/?/平滑過渡。讀元音/?? /的時(shí)候，雙頜盡量打開，嘴巴張大，像看病時(shí)對(duì)醫(yī)生張嘴說“啊”那樣;舌身下沉，想象嘴巴里含了一個(gè)燙山芋，想盡快把它吐出來的感覺。然后舌身向前頂，下頜收回，發(fā)元音/?/。注意兩個(gè)元音之間的過渡要平滑，音程占比是大約7:3。對(duì)于母語是中文的學(xué)習(xí)者來說，這個(gè)音標(biāo)經(jīng)常會(huì)由于/??/的發(fā)音不到位，而形成類似中文“愛”的發(fā)音。
仔細(xì)聽音頻，體會(huì)兩個(gè)音素構(gòu)成一個(gè)雙元音的結(jié)合方式。
