Voice作为声音讲时,基本上都是作为名词使用的.而utter没有声音这个意思.
作为动词:
Utter vt (用嘴)发音
Voice vt 讲出、说出
Utter作为动词有具体用嘴发出声音的意思.Voice则是抽象的讲出某件事的意思.请看下例:
He voiced concerns about Erickson to a bishop.他对主教说出了对Erickson的担心.
He voiced his conclusion.他讲出他的结论.
He uttered his voice 他发出他的声音.
He uttered strange sounds that nobody could understand 他发出别人不能理解的声音.
在句子里utter和voice不能互换.
