比喻：說了也沒人聽

adjective · B2
Not able to get your opinions, needs or worries noticed by the people who hold power, so that decisions are made about you without you.
沒有發言權的
核心畫面
Picture a mouth moving with nothing coming out of it. That gap — the shape is there, the sound is not — can be thought of as the whole word. English voice means two things at once, the sound from your throat and the say you have in a decision, so the same gap can be a throat that makes no sound, a group nobody in power hears, or a consonant made with the vocal cords switched off.

可以想成一張嘴在動，卻沒有東西出來。形狀在，聲音不在——這個空缺就像是整個字的核心。英文的 voice 同時有兩個意思：喉嚨出來的聲音，和你在一件事上說話的份量。所以同一個空缺，可以是發不出聲音的喉嚨，可以是講了沒人理的一群人，也可以是聲帶沒有振動的那個子音。From the word’s history
The word is simply voice plus -less, the ending that means without. Everything it can mean comes from which kind of voice is missing.
這個字就是 voice 加上 -less（沒有…）。它能有這麼多用法，關鍵只在於：少掉的是哪一種 voice。

語音學：聲帶沒有振動
這裡的 voice 縮小成很精確的一件事：聲帶的振動。少掉的就是那個嗡嗡聲，所以同樣是「缺了 voice」，只是缺的東西被定義得非常窄。

Used of a speech sound made without the vocal cords vibrating — for example the English consonants /p/, /t/, /k/, /s/ and /f/.
