one這個單詞裡的讀音為[wʌ]。母音字母在單詞裡的讀音比較複雜，因為英語裡只有五個純母音字母，而母音音素有二十個之多。母音字母在單詞中讀母音音素，子音字母在單詞中讀子音音素，理論上每個母音字母要有四種讀音才能滿足20個母音音素的讀音需要。關於字母Ｏ在單詞中的讀音歸納如下：
1）字母O讀[əu]
例如：no [nəu] hello [hə"ləu] home [həum] those [ðəuz] over ["əuvə] phone [fəun] open ["əupən] so [səu] nose [nəuz] broken ["brəukən] robot ["rəubɔt] code [kəud] close [kləuz] smoke [sməuk] October [ɔk"təubə] hope [həup] ago [ə"gəu] Rome [rəum] suppose [sə"pəuz] mobile ["məubil] notice ["nəutis]
2）字母O讀[u:]
例如：who [hu:] do[du:] improve [ɪm"pruːv] move [mu:v] lose [lu:z] canoe [kə"nu:]
3）字母O讀[ɔ]
例如：not [nɔt] clock [klɔk] forgot[fə"gɔt] doctor ["dɔktə] lock [lɔk] doll [dɔl] from [frɔm] sock [sɔk] shop [ʃɔp] hot [hɔt] fog [fɔg] hospital ["hɔspitl] job [dʒɔb] hobby ["hɔbi] problem ["prɔbləm] dollar["dɔlə] college ["kɔlidʒ] dolphin ["dɔlfin] soccer ["sɔkə] rock [rɔk] concert ["kɔnsət] song [sɔŋ] crop [krɔp] opposite ["ɔpəzit]
4)字母O在th/ ve/ n/m前讀[ʌ]
例如：one [wʌn] mother ["mʌðə] brother ["brʌðə] love [lʌv] some [sʌm] money ["mʌni] glove [glʌv] other ["ʌðə] Monday ["mʌndei] company ["kʌmpəni] another[ə"nʌðə] nothing ["nʌθiŋ] monkey ["mʌŋki] front [frʌnt] month [mʌnθ] comfortable ["kʌmfətəbl] wonder ["wʌndə]
5）字母I讀音例外詞:colour ["kʌlə] body ["bɔdi] woman ["wumən] popular ["pɔpjulə] opera ["ɔpərə] post [pəust] most[məust] both [bəuθ] pocket ["pɔkit] lost [lɔst]
