voice

1、voice 来自拉丁 vox"声音"，同族一大串：vocal 嗓音的、vocabulary 词汇（表）、vocation 职业、vowel 元音、invoke 调用、召唤。记住 vox/voc 就是"出声"。
2、读音 /vɔɪs/，和 choice（选择）完全同韵，只差开头的辅音，把 voice、choice 放在一起念两遍，拼写和读音都记住了。
3、voice 也能当动词，意思是"说出、表达"：voice your opinion 说出你的看法。名词还引申为"发言权"，have a voice in the decision 在决定里有话说。

voice

voice: [13] Voice comes via Old French vois from Latin vōx ‘voice’, whose other contributions to English include vocal [14], vociferous [17], and vowel. Its ultimate source is the Indo-European base *wek- ‘speak, say’, which also produced Latin vocāre ‘call’, ancestor of English vocabulary, vocation, etc.
=> vocal, vocation, vociferous, vowel

voice (n.)

Replaced Old English stefn. Meaning "ability in a singer" is first attested c. 1600. Meaning "expression of feeling, etc." (in reference to groups of people, etc., such as Voice of America) is recorded from late 14c.
